THS4303RGTT from Texas Instruments, in a VQFN-16-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 | VS- | power_in | Negative supply pin (one of four VS- pins, 1-4); dual supply ±1.5 V to ±2.5 V, or ground for single 3 V to 5 V supply. |
| 2 | VS- | power_in | Negative supply pin (one of four VS- pins, 1-4); dual supply ±1.5 V to ±2.5 V, or ground for single 3 V to 5 V supply. |
| 3 | VS- | power_in | Negative supply pin (one of four VS- pins, 1-4); dual supply ±1.5 V to ±2.5 V, or ground for single 3 V to 5 V supply. |
| 4 | VS- | power_in | Negative supply pin (one of four VS- pins, 1-4); dual supply ±1.5 V to ±2.5 V, or ground for single 3 V to 5 V supply. |
| 5 | VOUT | output | Amplifier output (one of four VOUT pins, 5-8) for the fixed gain of +10 V/V, with output current up to ±180 mA. |
| 6 | VOUT | output | Amplifier output (one of four VOUT pins, 5-8) for the fixed gain of +10 V/V, with output current up to ±180 mA. |
| 7 | VOUT | output | Amplifier output (one of four VOUT pins, 5-8) for the fixed gain of +10 V/V, with output current up to ±180 mA. |
| 8 | VOUT | output | Amplifier output (one of four VOUT pins, 5-8) for the fixed gain of +10 V/V, with output current up to ±180 mA. |
| 9 | VS+ | power_in | Positive supply pin (one of four VS+ pins, 9-12); dual supply ±1.5 V to ±2.5 V or single 3 V to 5 V, absolute maximum 6 V. |
| 10 | VS+ | power_in | Positive supply pin (one of four VS+ pins, 9-12); dual supply ±1.5 V to ±2.5 V or single 3 V to 5 V, absolute maximum 6 V. |
| 11 | VS+ | power_in | Positive supply pin (one of four VS+ pins, 9-12); dual supply ±1.5 V to ±2.5 V or single 3 V to 5 V, absolute maximum 6 V. |
| 12 | VS+ | power_in | Positive supply pin (one of four VS+ pins, 9-12); dual supply ±1.5 V to ±2.5 V or single 3 V to 5 V, absolute maximum 6 V. |
| 13 | NC | unconnected | No connect. |
| 14 | VIN- | power_in | Inverting input, which is the ground end of the internal 50 Ω Rg gain-setting resistor, and should have a very low inductance path to ground. |
| 15 | VIN+ | power_in | Noninverting input with 1.6 MΩ || 1 pF input impedance and common-mode range of VS-+1 V to VS+-1 V. |
| 16 | PD | input | Power-down input, active low, defaulting to the positive supply (power on); above 1.5 V the device is on, below 0.9 V it is off. |
| 17 | EP | passive | Exposed thermal pad (PowerPAD) that must be soldered to a thermally dissipative copper plane for power dissipation. |
