# TPA6100A2DGKR

**Texas Instruments** · Audio Amplifiers · VSSOP-8

TPA6100A2DGKR from Texas Instruments, in a VSSOP-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 | BYPASS | passive | BYPASS is the tap to the voltage divider for the internal mid-supply bias, set at VDD/4, and should be connected to a 0.1-µF to 1-µF low-ESR capacitor for best performance. |
| 2 | GND | power_in | GND is the ground connection for the device. |
| 3 | SHUTDOWN | input | SHUTDOWN is an active-low input that, when held low, places the device in a low supply current mode; its high-level input must be at least 0.6 x VDD and its low-level input at most 0.25 x VDD. |
| 4 | IN2- | input | IN2- is the inverting input for channel 2, with input impedance greater than 1 MΩ. |
| 5 | VO2 | output | VO2 is the audio output for channel 2. |
| 6 | VDD | power_in | VDD is the supply voltage terminal, operating over a recommended range of 1.6 V to 3.6 V with an absolute maximum of 4 V. |
| 7 | VO1 | output | VO1 is the audio output for channel 1. |
| 8 | IN1- | input | IN1- is the inverting input for channel 1, with input impedance greater than 1 MΩ. |
