THS4521ID 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 | VIN- | power_in | Inverting amplifier input. |
| 2 | VOCM | input | Common-mode voltage input that sets the output common-mode voltage. |
| 3 | VS+ | power_in | Amplifier positive power-supply input. |
| 4 | VOUT+ | output | Noninverting amplifier output. |
| 5 | VOUT- | output | Inverting amplifier output. |
| 6 | VS- | power_in | Amplifier negative power-supply input; VS- is tied together on multi-channel devices. |
| 7 | PD | input | Power-down pin: logic low puts the device into low-power mode, and logic high or open gives normal operation. |
| 8 | VIN+ | power_in | Noninverting amplifier input. |
