3PEAK · Operational Amplifier · MSOP-8

TP1282L1-VR from 3PEAK, in a MSOP-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 Output of amplifier A, which swings rail-to-rail.
2 -In A input Inverting input of amplifier A; the input common-mode voltage range extends to V- (rail-to-rail input range is not stated, only that it extends to V-).
3 +In A input Noninverting input of amplifier A; the input common-mode voltage range extends to V-.
4 -VS power_in Negative power supply; the absolute maximum supply voltage (+VS)-(-VS) is 40 V.
5 +In B input Noninverting input of amplifier B; the input common-mode voltage range extends to V-.
6 -In B input Inverting input of amplifier B; the input common-mode voltage range extends to V-.
7 Out B output Output of amplifier B, which swings rail-to-rail.
8 +VS power_in Positive power supply; the operating supply range is 4.5 V to 36 V.
