TL031ID

Texas Instruments · Pre-ordered Chips · SOIC-8

TL031ID 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 OFFSET N1 passive Input offset adjustment pin for trimming the input offset voltage; the TL031ID has on-chip offset-voltage trimming to 1.5 mV.
2 IN- input Inverting input of the amplifier.
3 IN+ input Non-inverting input of the amplifier.
4 VCC- power_in Negative power supply; the recommended supply range is ±5 V to ±15 V and the absolute maximum VCC- is −18 V.
5 OFFSET N2 passive Input offset adjustment pin for trimming the input offset voltage, used together with OFFSET N1.
6 OUT output Amplifier output; each output is rated at 40 mA maximum, and the output may be shorted to either supply for unlimited duration at or below 25°C.
7 VCC+ power_in Positive power supply; the absolute maximum VCC+ is 18 V and the recommended supply range is ±5 V to ±15 V.
8 NC unconnected Do not connect.
