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

THS4151ID 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 input of the fully differential amplifier; input voltage must stay within ±VCC. |
| 2 | VOCM | input | Output common-mode voltage control input, where the output common-mode voltage VOC equals VOCM. |
| 3 | VCC+ | power_in | Positive supply; VCC+ to VCC- is 5 V single supply up to ±15 V dual supply (absolute maximum ±16.5 V). |
| 4 | VOUT+ | output | Non-inverting output of the differential output pair; output current is limited to 150 mA absolute maximum. |
| 5 | VOUT- | output | Inverting output of the differential output pair; output current is limited to 150 mA absolute maximum. |
| 6 | VCC- | power_in | Negative supply (ground in single-supply operation); VCC+ to VCC- is up to ±16.5 V absolute maximum. |
| 7 | NC | unconnected | No internal connection (THS4151 has no shutdown function; this pin is PD on the THS4150). |
| 8 | VIN+ | power_in | Non-inverting input of the fully differential amplifier; input voltage must stay within ±VCC. |
