THS4031IDR

Texas Instruments · Operational Amplifier · SOIC-8

THS4031IDR 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 input Voltage offset adjust input; connect external potentiometer between pins 1 and 8 with wiper tied to VCC- to trim input offset voltage.
2 IN- input Inverting input terminal for analog signal input.
3 IN+ input Noninverting input terminal for analog signal input.
4 VCC- power_in Negative power supply; recommended operating range ±4.5V to ±16V for dual-supply operation.
5 NC unconnected No connection; leave unconnected.
6 OUT output Amplifier output with maximum output current drive of 200mA and voltage swing of ±12.9V at ±15V supply with 250Ω load.
7 VCC+ power_in Positive power supply; recommended operating range ±4.5V to ±16V for dual-supply operation.
8 NULL input Voltage offset adjust input; connect external potentiometer between pins 1 and 8 with wiper tied to VCC- to trim input offset voltage.
