# THS4051ID

**Texas Instruments** · Operational Amplifier · SOIC-8

THS4051ID 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 | NULL | passive | Offset null terminal for input offset voltage trim, used with the external null network shown in the evaluation board schematic (Figure 58). |
| 2 | IN− | input | Inverting input of the voltage feedback amplifier. |
| 3 | IN+ | input | Non-inverting input of the voltage feedback amplifier. |
| 4 | VCC− | power_in | Negative supply rail; recommended operation is ±4.5 V to ±16 V dual supply or 9 V to 32 V single supply. |
| 5 | NC | unconnected | No internal connection. |
| 6 | OUT | output | Amplifier output, capable of 100 mA typical drive; absolute maximum output current is 150 mA. |
| 7 | VCC+ | power_in | Positive supply rail; recommended operation is ±4.5 V to ±16 V dual supply or 9 V to 32 V single supply. |
| 8 | NULL | passive | Offset null terminal for input offset voltage trim, used with the external null network shown in the evaluation board schematic (Figure 58). |
