ADEMA124

AD7124-8BBCPZ is an Analog Devices 24-bit sigma-delta ADC with 8 differential (15 pseudo-differential) inputs in 32-lead LFCSP — for multichannel precision measurement where board space and power both matter: PLC/DCS analog input modules, smart transmitters and portable instrumentation. Three user-selectable power modes trade throughput against noise (down to 255 µA with 24 nV rms at gain 128), the on-chip PGA offers gains 1 to 128 with rail-to-rail inputs, and the integrated 2.5 V reference plus dual excitation current sources cut external BOM for RTD and bridge sensors. Simultaneous 50/60 Hz rejection suits noisy industrial environments. Selection advice: the BBCPZ code is the 32-lead LFCSP tray version — for 4-channel designs the AD7124-4 is the pin-family sibling; the per-channel programmable digital filters let one hardware platform serve both fast and high-resolution channels. The on-chip diagnostics aid functional-safety designs. Parameters verified against Analog Devices documentation.

ADEMA127 is a 7-channel, 24-bit simultaneously sampling sigma-delta ADC from Analog Devices for precision three-phase four-wire energy metering, converting seven voltage and current inputs at the same instant at up to 64 kSPS with up to 105 dB SNR, with high-impedance differential inputs over a plus-minus 1.2 V peak range, a 5 ppm per °C internal voltage reference, per-channel DSP for gain, phase, and offset compensation, an integrated digital integrator and second-order high-pass filter for Rogowski coils, sinc compensation with low-pass filtering and decimate-by-2 that extends usable analog bandwidth by up to 70 percent, and a 4-wire SPI interface with bidirectional CRC and daisy-chain support in a 32-lead 5 mm x 5 mm LFCSP. Simultaneous sampling is the selection point: all channels are captured at the same instant, so active and reactive energy stay accurate across phases without the skew error of multiplexed converters, and the on-chip DSP removes the external calibration and compensation parts that older metering front ends needed. The business gain is a faster, cheaper meter design: one ADC covers three phases, neutral, and a tamper channel, preloaded DSP filter coefficients shorten firmware work, 0.5 ms fast start-up suits breakers and protection relays, and tamper-detect mode with low-power battery backup protects revenue metering, at only 18 mW with all seven channels active. Evidence: the Analog Devices ADEMA124/ADEMA127 data sheet Rev. A defines this device with its 7-channel configuration, 105 dB SNR, and -40 °C to +125 °C operating range, and Analog Devices lists ADEMA127 as recommended for new designs; the orderable form is ADEMA127ACPZ in a 32-lead LFCSP. Selection advice: choose ADEMA127 over ADEMA124 when the meter needs three-phase four-wire measurement with neutral current plus an auxiliary or tamper channel in one device; drop to ADEMA124 when four channels cover the design; the same device works with current transformers, shunts, voltage dividers, or Rogowski coils, and it daisy-chains with ADE9112 and ADE9113 isolated ADCs for isolated channels.

AD7190BRUZ is an Analog Devices 24-bit sigma-delta ADC with internal PGA in 24-lead TSSOP — the established weigh-scale and strain-gauge front end: the CN0102 reference design builds a complete precision weigh scale around it with only input filters added. Ultralow-noise performance from 4.7 Hz to 4.8 kHz output data rates covers both slow precision and faster hopper-scale applications, the internal PGA interfaces load cells directly, and the bridge power-down switch minimizes system power. On-chip temperature sensor and burnout detection complete the transducer interface. Selection advice: the BRUZ code is the TSSOP-24 tube version (-40 to +105 °C) — for 8-channel multiplexed weigh systems step up to the AD7124-8 on this site; the AD7190 stays the pick for dedicated single-bridge precision channels. Match the full BRUZ code for package and temperature grade. Parameters verified against Analog Devices documentation.

ADuM7801ARWZ is an Analog Devices isolated sigma-delta analog-to-digital converter — for shunt-based current sensing in high-voltage systems: second-order Σ-Δ modulator with single-bit data stream output up to 25MHz, on-chip iCoupler digital isolation, ±250mV pseudodifferential input (±320mV full-scale), 4.0V to 5.5V high-side supply, 3V to 5.5V controller-side supply, 88dB SNR at 97.6kSPS (256x decimation, sinc3 filter), 16-lead SOIC package. Integrating the modulator and isolation in one package eliminates the optocoupler-plus-ADC two-chip solution — the CMOS isolation path is faster and more stable over temperature than optocouplers; pin compatibility with the 50MHz ADuM7811 lets one PCB serve both clock rates. Business impact: as SiC/GaN switches get faster, current-sense bandwidth becomes the control-loop bottleneck — the 25MHz ADuM7801 future-proofs motor-drive and solar-inverter designs. Selection advice: the ARWZ code is the 16-lead SOIC — for evaluation use the EV-ADuM7801-8FMCZ with ACE software; for 50MHz operation consider the pin-compatible ADuM7811.

Texas Instruments lists ADS1115IDGSR as an ACTIVE 16-bit delta-sigma ADC in VSSOP-10, with 860 SPS sampling, 4 multiplexed channels and I2C interface. The 16-bit resolution is the procurement-relevant advantage: it resolves small sensor signals that a 10- or 12-bit converter would bury in quantization noise, which is why this part is the default choice for precision data-acquisition front ends. Selection advice: the IDGSR suffix pins the VSSOP-10 package on tape and reel — the ADS1115 also ships in other packages, so match the full code to your layout. Four multiplexed inputs versus the two-channel ADS1113 and single-ended/differential options are the family decision points; confirm your channel count and interface (I2C here, not SPI) against the datasheet before substituting. Parameters verified against the TI official product page. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

ADS1220IPWR is a 24-bit precision analog-to-digital converter from Texas Instruments in a 16-pin TSSOP package, with an SPI interface — for sensor measurement in weigh scales, thermocouple systems and industrial data acquisition. The 24-bit delta-sigma core is the selection point: it resolves microvolt-level sensor signals that lower-resolution converters cannot, with the digital filter handling noise rejection. Selection advice: the IPWR suffix denotes TSSOP-16 on tape and reel — match the full code to your layout. Confirm your required sample rate and input configuration (differential vs single-ended, PGA gain) against the datasheet before committing.

ADS124S08IPBSR is a Texas Instruments 24-bit delta-sigma ADC with 12-channel multiplexer in 32-pin TQFP — for dense multichannel sensor measurement: the TIDA-01434 reference design uses it to build high-channel-density PLC analog input modules. As low as 280 µA consumption, 19 nV rms PGA noise at gain 128, programmable data rates 2.5 SPS to 4 kSPS with simultaneous 50/60 Hz rejection at low rates, an integrated 2.5 V low-drift reference, and dual matched 10 µA–2 mA excitation current sources for direct RTD biasing with lead-resistance cancellation. Sensor burnout detection and four GPIOs complete the input module. Selection advice: the IPBSR code is the TQFP-32 reel version — for 6-channel designs the ADS124S06 is the pin-family sibling; against the ADS1256 on this site, the ADS124S08 trades maximum data rate for integration (reference plus IDACs on chip) and lower power. The -50 to +125 °C range suits harsh cabinets. Parameters verified against Texas Instruments documentation.

ADS1256IDB is a Texas Instruments 24-bit delta-sigma ADC with 8-channel multiplexer in 28-pin SSOP — the long-standing reference for high-resolution industrial measurement: weigh scales, scientific instrumentation and process control. Up to 23 bits noise-free resolution with ±0.0010% nonlinearity, data rates to 30 kSPS with single-cycle settling for fast channel cycling, a chopper-stabilized input buffer and low-noise PGA (27 nV input-referred) with gains 1 to 64. Self and system calibration run at every PGA setting. Selection advice: the IDB code is the SSOP-28 tube version — for 4 kSPS multichannel sensor work the ADS124S08 on this site integrates the reference and IDACs; the ADS1256 keeps the external-reference architecture for designs that need a system-level precision reference. The 5 V-tolerant SPI suits 3.3 V hosts directly. Parameters verified against Texas Instruments documentation.

PCM1808 is a Texas Instruments 24-bit stereo audio ADC in 14-pin TSSOP — for digitizing line-level audio in AV receivers, digital TVs and USB audio interfaces: 99-dB SNR, -93-dB THD+N, 8-kHz to 96-kHz sampling, single-ended 3-Vpp inputs with on-chip antialias filter. The 64x-oversampling delta-sigma modulator with decimation and DC-removing high-pass filter needs only 5-V analog plus 3.3-V digital supplies, and master/slave I2S or left-justified interface drops straight onto any audio SoC. Selection advice: the hardware-controlled single-ended input suits cost-sensitive line capture — for differential inputs or 192-kHz rates step up the PCM1800 family; pair with the PCM5102A DAC on this site for a complete low-cost codec signal chain. Power-down by halting the system clock simplifies standby design. Parameters verified against Texas Instruments documentation.

AD4003BRMZ is an Analog Devices 18-bit, 2 MSPS successive-approximation ADC in 10-lead MSOP — for precision data acquisition that needs both speed and DC accuracy: automatic test equipment, portable instruments and machine automation. ±1 LSB maximum INL with 100.5 dB SNR and -123 dB THD at 1 kHz, no latency or pipeline delay with first conversion accurate, and a high-Z input mode plus long acquisition phase that lets low-power precision amplifiers drive it directly — no dedicated high-speed ADC driver required. Input span compression runs the driver and ADC from common rails without a negative supply. Selection advice: the BRMZ code is the MSOP-10 version — for 16-bit at lower cost the AD4000 is the family sibling; the 1.8 V single supply with 1.71–5.5 V logic interface suits battery-powered field instruments. Daisy-chainable SPI simplifies multichannel layouts. Parameters verified against Analog Devices documentation.
