**Texas Instruments** · Audio Amplifiers · SON-8-EP(3x3)

TPA2005D1DRBR from Texas Instruments, in a SON-8-EP(3x3). 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 | SHUTDOWN | input | Shutdown terminal, active low logic with input thresholds VIL=0 to 0.8 V and VIH=2 to VDD V. |
| 2 | NC | unconnected | No internal connection. |
| 3 | IN+ | input | Positive differential input with common mode voltage range 0.5 to VDD-0.8 V. |
| 4 | IN- | input | Negative differential input with common mode voltage range 0.5 to VDD-0.8 V. |
| 5 | VO+ | output | Positive BTL output with minimum load resistance 3.2 Ω at VDD 2.5-4.2 V or 6.4 Ω at VDD 4.2-5.5 V. |
| 6 | VDD | power_in | Power supply input, operating range 2.5 to 5.5 V, requires 0.1 µF decoupling capacitor within 2 mm. |
| 7 | GND | power_in | High-current ground with exposed thermal die pad connection to ground plane. |
| 8 | VO- | output | Negative BTL output with minimum load resistance 3.2 Ω at VDD 2.5-4.2 V or 6.4 Ω at VDD 4.2-5.5 V. |
| 9 | Thermal Pad | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
