LM386N-1/NOPB

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.

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.

TAS6424Q1 is a Texas Instruments AEC-Q100 automotive 4-channel Class-D audio amplifier — for premium in-vehicle infotainment: head units, external amplifiers and sound systems. Four bridge-tied-load channels with up to 2.1MHz switching frequency, AC diagnostics for tweeter open/short detection with impedance measurement, and CISPR25 Level 5 EMC compliance. Heat evidence: automotive audio is moving to fully digital Class-D as OEMs chase efficiency and diagnostic coverage — tweeter diagnostics are now a checklist item for premium trims. Selection advice: the 4-channel BTL configuration suits standard 4-speaker systems — for subwoofer drive the parallel-BTL mode doubles current; the 2.1MHz switching keeps AM-band interference out. AEC-Q100 qualified for automotive. Parameters verified against Texas Instruments documentation.

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.

LM358N/NOPB is a Texas Instruments dual-channel 32 V op amp in PDIP-8 — for general analog signal conditioning: sensor buffering, comparators and active filters. Single-supply 3 V to 32 V operation with 1 MHz bandwidth is the selection point: among the lowest-cost dual op amps that work from a single rail. Selection advice: the N/NOPB denotes PDIP-8 — the breadboard-friendly variant; for SMT, the SOIC variant is the pick. 2 mV input offset suits non-precision tasks — for precision sensing, modern zero-drift op amps are the step up. TI lists this part as ACTIVE. 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.

LM393N/NOPB is a Texas Instruments low-power, low-offset dual voltage comparator in PDIP-8 — for threshold detection: battery monitors, zero-crossing detectors and window comparators. 0.4 mA supply current per channel with 2 V to 36 V supply is the selection point: always-on comparison at micropower budgets. Selection advice: the N/NOPB denotes PDIP-8 — the breadboard-friendly variant; for SMT, the SOIC variant is the pick. Open-collector output needs a pull-up resistor — plan for it in your schematic. TI lists this part as ACTIVE. 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.

NE555P is a Texas Instruments NE555 precision timer in PDIP-8, tube packaging — 4.5 V to 16 V supply, timing from microseconds to hours set by two resistors and a capacitor, 200 mA output that drives relays, buzzers and LEDs directly, TTL-compatible, monostable and astable operation. The P suffix is the selection point: PDIP-8 through-hole for breadboard, teaching and legacy through-hole assembly — the same 555 ships in SOIC and other SMD packages under different suffixes, so match the full NE555P code to your board. Selection advice: the 200 mA direct-drive output is why the 555 survives in an MCU world — no transistor stage needed for small loads. For battery-powered timing, note the milliamp supply current of the bipolar 555; the CMOS LMC555/TLC555 variants cut that by orders of magnitude. As a jellybean part, require lot traceability against remarked stock. Evidence: TI NE555 product page confirms PDIP-8, 4.5–16 V supply and 200 mA output drive. Match the full NE555P code.
