LM2904A-SO1R-S

3PEAK · Operational Amplifier · SOP-8

LM2904A-SO1R-S from 3PEAK, in a SOP-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-.
3 +IN A input Non-inverting input of amplifier A; the input common-mode voltage range extends to V-, and inputs are ESD-protected diodes that require input current limited to less than 10 mA if the input extends more than 300 mV beyond the supply.
4 -VS power_in Negative supply rail (V-); the device operates from 3 V to 36 V single supply or ±1.5 V to ±18 V split supply.
5 +IN B input Non-inverting input of amplifier B; the input common-mode voltage range extends to V-, and inputs are ESD-protected diodes that require input current limited to less than 10 mA if the input extends more than 300 mV beyond the supply.
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 supply rail (V+); the device operates from 3 V to 36 V single supply or ±1.5 V to ±18 V split supply, with absolute maximum supply voltage of 40 V.
