# THS4225DGK

**Texas Instruments** · Operational Amplifier · VSSOP-8

THS4225DGK 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 | REF | input | Reference node for the power-down control; the datasheet gives the power-down and enable thresholds relative to REF (enable at REF+1.8 V minimum, power down at REF+1.0 V maximum). |
| 2 | IN− | input | Inverting amplifier input; the input common-mode voltage range is VS− + 1.1 V to VS+ − 1.1 V. |
| 3 | IN+ | input | Non-inverting amplifier input; the input common-mode voltage range is VS− + 1.1 V to VS+ − 1.1 V. |
| 4 | VS− | power_in | Negative power supply pin; supports single supply down to 2.7 V minimum or dual supplies of ±1.35 V to ±7.5 V. |
| 5 | NC | unconnected | No internal connection. |
| 6 | VOUT | output | Amplifier output with rail-to-rail swing, specified at VO = ±4.8 V with RL = 2 kΩ on ±5 V supplies. |
| 7 | VS+ | power_in | Positive power supply pin; operating range is 3 V to 15 V, with an absolute maximum supply voltage of 16.5 V. |
| 8 | PD | input | Power-down control; PD at or below REF+1.0 V powers the amplifier down, and PD at or above REF+1.8 V enables it. |
