TP2312-SR

3PEAK · Precision Op Amps · SOIC-8

TP2312-SR from 3PEAK, 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 Out A output Amplifier A output, whose voltage range extends to within mV of each supply rail.
2 -In A input Inverting input of amplifier A.
3 +In A input Non-inverting input of amplifier A.
4 -Vs power_in Negative power supply, normally tied to ground, with V+ to V- between 2.2V and 5.5V and a 0.1μF bypass capacitor if not grounded.
5 +In B input Non-inverting input of amplifier B.
6 -In B input Inverting input of amplifier B.
7 Out B output Amplifier B output, whose voltage range extends to within mV of each supply rail.
8 +Vs power_in Positive power supply, typically 2.2V to 5.5V, with a 0.1μF bypass capacitor close to the part.
