TPA302D

Texas Instruments · Audio Power OpAmps · SOIC-8

TPA302D from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VO1 output Output of amplifier channel 1, which can swing to VDD - 1 V and drive 8-Ω or 32-Ω loads.
2 SHUTDOWN input Shutdown control that must be held low for normal operation; pulling it high mutes the outputs and drops supply current to about 0.6 µA, and it must never be left unconnected.
3 BYPASS passive Midrail (VDD/2) bypass node fed from an internal 25-kΩ source, where a 0.1-µF to 1-µF low-ESR capacitor CB sets the start-up rate and reduces midrail noise.
4 IN2 input Inverting input of amplifier channel 2, where the effective impedance at the inverting node should be kept between 5 kΩ and 20 kΩ.
5 VO2 output Output of amplifier channel 2, which can swing to VDD - 1 V and drive 8-Ω or 32-Ω loads.
6 VDD power_in Supply voltage input, specified for 2.7 V to 5.5 V with an absolute maximum of 6 V.
7 GND power_in Ground reference for the device; the datasheet states no electrical limit for this pin.
8 IN1 input Inverting input of amplifier channel 1, where the effective impedance at the inverting node should be kept between 5 kΩ and 20 kΩ.
