# TPA0253DGQR

**Texas Instruments** · Audio Amplifiers · HVSSOP-10-EP-0.5mm

TPA0253DGQR from Texas Instruments, in a HVSSOP-10-EP-0.5mm. 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 | FILT_CAP | passive | Power supply filter capacitor terminal. |
| 2 | SHUTDOWN | input | Shutdown control input, TTL-compatible; logic high enables amplifier, logic low enters shutdown mode consuming 1 µA typical. |
| 3 | VDD | power_in | Positive power supply input pin, requires 2.5 V to 5.5 V for normal operation. |
| 4 | BYPASS | input | Midrail bias voltage reference terminal; connect 0.47 µF bypass capacitor to ground. |
| 5 | RIN | input | Right-channel audio input terminal with 50 kΩ input impedance (CMOS high-impedance input). |
| 6 | RO/MO+ | output | Right-channel audio output (stereo single-ended mode) or positive output (mono BTL mode). |
| 7 | ST/MN | input | Stereo/Mono mode selection input; logic high selects stereo SE mode, logic low selects mono BTL mode. |
| 8 | GND | power_in | Ground reference terminal for all device currents. |
| 9 | LIN | input | Left-channel audio input terminal with 50 kΩ input impedance (CMOS high-impedance input). |
| 10 | LO/MO- | output | Left-channel audio output (stereo single-ended mode) or negative output (mono BTL mode). |
| 11 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
