THS4221D from Texas Instruments, in a SOIC-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 | NC | unconnected | No internal connection; leave unconnected. |
| 2 | IN− | input | Inverting input of the amplifier; the input common-mode voltage range is VS− + 1.1 V to VS+ − 1.1 V. |
| 3 | IN+ | input | Non-inverting input of the amplifier; the input common-mode voltage range is VS− + 1.1 V to VS+ − 1.1 V. |
| 4 | VS− | power_in | Negative power supply; supply is 2.7 V to 15 V single-supply or ±1.35 V to ±7.5 V dual-supply, with absolute maximum supply voltage of 16.5 V. |
| 5 | NC | unconnected | No internal connection; leave unconnected. |
| 6 | VOUT | output | Amplifier output; output current is rated at 100 mA (absolute maximum), with rail-to-rail swing of ±4.8 V at RL = 2 kΩ. |
| 7 | VS+ | power_in | Positive power supply; supply is 2.7 V to 15 V single-supply or ±1.35 V to ±7.5 V dual-supply, with absolute maximum supply voltage of 16.5 V. |
| 8 | NC | unconnected | No internal connection; leave unconnected. |
