**Texas Instruments** · Audio Amplifiers · SOIC-16-300mil

DRV134UA from Texas Instruments, in a SOIC-16-300mil. 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 | NC | unconnected | No internal connection; this pin should be left unconnected. |
| 2 | NC | unconnected | No internal connection; this pin should be left unconnected. |
| 3 | -Vo | output | Inverted balanced differential output of the line driver. |
| 4 | -Sense | input | Inverting sensing input. |
| 5 | Gnd | power_in | Ground; the source common should be connected as close as possible to this pin, since ground offset errors in the source degrade system performance. |
| 6 | VIN | power_in | Signal input, which should be driven by a low impedance source such as an op amp or buffer. |
| 7 | NC | unconnected | No internal connection; this pin should be left unconnected. |
| 8 | NC | unconnected | No internal connection; this pin should be left unconnected. |
| 9 | NC | unconnected | No internal connection; this pin should be left unconnected. |
| 10 | NC | unconnected | No internal connection; this pin should be left unconnected. |
| 11 | V- | power_in | Negative supply, specified from -4.5 V to -18 V. |
| 12 | V+ | power_in | Positive supply, specified from +4.5 V to +18 V. |
| 13 | +Sense | input | Non-inverting sensing input. |
| 14 | +Vo | output | Balanced differential output of the line driver. |
| 15 | NC | unconnected | No internal connection; this pin should be left unconnected. |
| 16 | NC | unconnected | No internal connection; this pin should be left unconnected. |

## CAD (KiCad official)

- Symbol: `DRV134UA`
- Footprint: `Package_SO:SOIC-16_3.9x9.9mm_P1.27mm`
- 3D model: SOIC-16-300mil (KiCad packages3D, STEP)
- 3D model files: `drv134ua-etched.step` / `drv134ua-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `drv134ua.step` / `drv134ua.glb` are the bare package body.
