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

THS4521IDGKT 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 | VIN- | power_in | Inverting amplifier input with input voltage range from (VS-) - 0.7 V to (VS+) + 0.7 V. |
| 2 | VOCM | input | Common-mode voltage input with voltage range from (VS-) - 0.7 V to (VS+) + 0.7 V. |
| 3 | VS+ | power_in | Positive power-supply input with recommended operating range of 2.7 to 5.4 V. |
| 4 | VOUT+ | output | Noninverting amplifier output with rail-to-rail voltage swing and maximum output current ±100 mA. |
| 5 | VOUT- | output | Inverting amplifier output with rail-to-rail voltage swing and maximum output current ±100 mA. |
| 6 | VS- | power_in | Negative power-supply input and ground reference tied together on multi-channel devices. |
| 7 | PD | input | Power-down control input; logic low activates low-power mode (20 μA typical), logic high or open circuit for normal operation. |
| 8 | VIN+ | power_in | Noninverting amplifier input with input voltage range from (VS-) - 0.7 V to (VS+) + 0.7 V. |
