TAS6424Q1

LM386N-1/NOPB is a Texas Instruments 700 mW mono AB-class audio power amplifier, 5–18 V supply, in 8-pin PDIP — for small speakers: intercoms, toys and portable radios. The minimal external parts (gain set by one capacitor) is the selection point: audio output with almost no support circuitry. Selection advice: the N-1/NOPB is the current orderable code — the bare LM386N-1 suffix is obsolete, so always order the /NOPB; for higher power or stereo, modern Class-D amplifiers are far more efficient. TI lists this order code as Active. Parameters verified against the TI official product page.

TAS2564 is a Texas Instruments 7-W digital-input Class-D smart amplifier in 36-ball DSBGA — for smartphones, wireless speakers and portable devices where the speaker must play louder without damage: integrated 13-V Class-H boost (256-level, algorithmically controlled), real-time speaker voltage/current sense for excursion and thermal protection, 110-dB SNR, I2S/TDM plus I2C with MCLK-free operation. Battery-tracking peak limiter with brownout prevention holds headroom across the full discharge curve; up to four devices share one bus. Selection advice: this is the integrated-boost smart amp — for external-boost designs the TAS2770 in QFN is easier to assemble than the 0.4-mm-pitch DSBGA; against the non-boost MAX98357A on this site, the TAS2564 plays markedly louder from the same battery at higher system cost. Configure via PurePath Console GUI. Parameters verified against Texas Instruments documentation.

TAS5805M is a Texas Instruments 23-W digital-input stereo Class-D amplifier in 32-pin HTSSOP — for smart speakers, soundbars and IoT audio where the amplifier must also do the audio processing: I2S/TDM digital input, integrated 96-kHz audio DSP with 15 biquads per channel, 3-band DRC, volume, mixing and level metering. Closed-loop architecture needs only 8 passives versus 31 for open-loop designs, and inductorless operation (ferrite bead) up to 10 W/ch shrinks the board. Selection advice: this is the DSP-equipped upgrade path from TAS5707/TAS5733L/TAS5751M per TI transition guide — for higher 35-W output the pin-different TAS5822M is the step up; for analog-input designs without DSP the TPA3116D2 on this site costs less. 16.5-mA quiescent at 13.5 V suits battery-powered portable speakers. Parameters verified against Texas Instruments documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

TPA3116D2 is a Texas Instruments 50-W stereo Class-D audio amplifier in 32-pin HTSSOP — for powered speakers, soundbars and aftermarket automotive audio where high output must come without a heatsink: 2x50 W into 4 ohms at 21 V, 4.5-V to 26-V supply range, over 90% efficiency with low idle loss. The feedback power-stage architecture delivers high PSRR so the power supply can be simpler and cheaper, while AM-avoidance switching frequencies (up to 1.2 MHz, master/slave sync) keep multi-amp systems clean. Selection advice: this is the 50-W member of the TPA31xxD2 family sharing one footprint — for 30-W designs the TPA3118D2 on this site drops into the same PCB, and for 15-W the TPA3130D2; the DAD suffix is the pad-up HTSSOP, DAP the pad-down. Programmable power limit and full fault reporting (overvoltage, overtemperature, DC-detect, short-circuit) suit unattended commercial installs. Parameters verified against Texas Instruments documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

TPA3118D2 is a Texas Instruments 30-W stereo (60-W mono) Class-D audio amplifier in 32-pin HTSSOP — for TVs, powered speakers and soundbars where 30 W per channel is the sweet spot: 2x30 W into 8 ohms at 24 V, 4.5-V to 26-V supply, pad-down package that uses the PCB plane as heatsink (no external heatsink). Same TPA31xxD2 family and footprint as the TPA3116D2, with AM-avoidance switching up to 1.2 MHz and full self-protection with error reporting. Selection advice: shares the PCB footprint with the 50-W TPA3116D2 and 15-W TPA3130D2 on this site — one layout covers three power tiers; the DAP suffix is the pad-down HTSSOP for heatsink-free builds, DAD the pad-up. For battery systems needing lower idle draw, the TPA3128D2 is TI next generation. Parameters verified against Texas Instruments documentation.

MAX98357A is an Analog Devices 3.2-W I2S digital-input Class-D amplifier in 16-pin TQFN (also 9-pin WLP) — for adding speaker output to any microcontroller with I2S: ESP32 voice assistants, Raspberry Pi audio HATs and portable IoT devices. 2.5-V to 5.5-V single supply, 3.2 W into 4 ohms at 5 V, no MCLK required, 8-kHz to 96-kHz sample rates, and filterless outputs that need only one bypass capacitor (4.32 mm2 solution). Selection advice: the A variant takes standard I2S — for left-justified data choose the MAX98357B; against TI digital-input amps on this site, the MAX98357A wins on board area and MCLK-free simplicity for sub-5-W designs, while the TAS5805M is the pick when DSP/EQ is needed. Five pin-selectable gains (3/6/9/12/15 dB) and left/right/mono-mix output suit single-speaker products. Parameters verified against Analog Devices documentation.

TDA7294V is a DMOS audio power amplifier from STMicroelectronics in a Multiwatt-15 package, for high-fidelity audio applications — Hi-Fi amplifiers, active speakers and car audio. Its advantage is the DMOS output stage: high output current with built-in thermal shutdown and short-circuit protection, which keeps a high-power audio design robust without elaborate discrete protection. Selection advice: the V suffix denotes the Multiwatt-15 vertical package — board mounting and heatsinking are integral to this part, so follow the datasheet mechanical and thermal guidance. High-power audio layouts are sensitive to grounding and supply decoupling; confirm your PCB follows the reference design.

TPA6304QDDVRQ1 is a Texas Instruments automotive four-channel Class-D audio amplifier in 44-pin HTSSOP with PowerPAD, tape and reel — 45 W per channel, 2.1 MHz PWM switching above the AM band, AEC-Q100 Grade 1 (-40 °C to +125 °C), 4.5 V to 18 V supply with load-dump protection, I2C diagnostics and spread-spectrum EMI control. The 2.1 MHz switching is the selection point: it clears the AM band so the output filter shrinks and CISPR25-L5 compliance gets easier in head-unit designs. Selection advice: the Q1 suffix is the automotive-qualified grade — DDV is the 44-HTSSOP PowerPAD package and R denotes reel; for non-automotive designs the commercial TPA32xx family may cost less. DigiKey lists this exact code as Active. Evidence: the TI TPA6304-Q1 official datasheet confirms the AEC-Q100 rating and package, and DigiKey confirms the ordering code as Active.

ADS7846 is a Texas Instruments 4-wire resistive touch screen controller in 16-pin TSSOP — the industry-standard part behind two decades of PDAs, point-of-sale terminals and portable instruments: 2.2 V to 5.25 V operation, internal 2.5 V reference, direct battery measurement from 0 V to 6 V, on-chip temperature and touch-pressure measurement, SPI/QSPI 3-wire interface, auto power-down, under 0.75 mW typical at 2.7 V, 125 kHz throughput, -40 to +85 °C. The pin-compatible upgrade path is the selection point: it drops into ADS7843 sockets with only software changes, adding battery and temperature measurement the older part lacks — which is why it remains the default choice for resistive-touch retrofits and long-life industrial designs. Selection advice: for new designs needing 1.5 V digital I/O, the TSC2046 on this site is the pin-compatible successor; the TSSOP-16 is the standard package, with QFN-16 and VFBGA-48 for space-constrained boards. Parameters verified against Texas Instruments documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

AM2434BSDFHIALVR is a Texas Instruments Sitara AM243x high-performance MCU: up to four 800 MHz Arm Cortex-R5F cores, a 400 MHz Cortex-M4F, and dual gigabit PRU-ICSSG industrial-communication subsystems in a 441-ball FCBGA (17.2 x 17.2 mm). It is TI's consolidation play for factory automation — the R5F cluster delivers deterministic servo-loop control while the PRU-ICSSG runs full protocol stacks for EtherCAT target, PROFINET device and EtherNet/IP adapter on the same silicon, replacing architectures that needed an MCU plus an external industrial-Ethernet ASIC or FPGA. Heat evidence: the AM243x is TI's mainstream platform for servo drives and remote I/O modules, and its datasheet remains under active revision (Rev. J, 2026), signaling continued TI investment in the family. Selection advice: the full orderable encodes silicon revision, feature configuration, temperature grade and the ALV 441-ball FCBGA package on tape and reel — match it character-for-character; the ALX 293-ball FCCSP is a smaller, footprint-incompatible alternative, and R5F count plus PRU features vary across AM2431/32/34.
