**Texas Instruments** · Differential Amplifiers · MSOP-8

THS4551IDGKT from Texas Instruments, in a MSOP-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 | IN- | input | Inverting (negative) amplifier input with maximum differential voltage of ±1V. |
| 2 | VOCM | input | Common-mode voltage control input. |
| 3 | VS+ | power_in | Positive power-supply input; recommended range 2.7V to 5.4V. |
| 4 | OUT+ | output | Noninverting (positive) amplifier output. |
| 5 | OUT- | output | Inverting (negative) amplifier output. |
| 6 | VS- | power_in | Negative power-supply input. |
| 7 | PD | input | Power-down control; logic low = power-off mode, logic high = normal operation. |
| 8 | IN+ | input | Noninverting (positive) amplifier input with maximum differential voltage of ±1V. |
