LM2904A-VR

3PEAK · Operational Amplifier · MSOP-8

LM2904A-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 per the datasheet.
2 −In A input Inverting input of amplifier A.
3 +In A input Non-inverting input of amplifier A; the input common-mode voltage range extends to -VS.
4 −VS power_in Negative power supply; total supply (+VS) - (-VS) is 3 V to 36 V (or ±1.5 V to ±18 V).
5 +In B input Non-inverting input of amplifier B.
6 −In B input Inverting input of amplifier B.
7 Out B output Output of amplifier B, which swings rail-to-rail per the datasheet.
8 +VS power_in Positive power supply; total supply (+VS) - (-VS) is 3 V to 36 V (or ±1.5 V to ±18 V).
