LM324A-SR

3PEAK · Operational Amplifier · SOIC-14

LM324A-SR from 3PEAK, in a SOIC-14. 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 range extends to V- (ground).
3 +IN A input Non-inverting input of amplifier A; the input common-mode range extends to V- (ground).
4 +VS power_in Positive supply, specified from 3V to 36V (absolute maximum supply 40V).
5 +IN B input Non-inverting input of amplifier B; the input common-mode range extends to V- (ground).
6 -IN B input Inverting input of amplifier B; the input common-mode range extends to V- (ground).
7 OUT B output Output of amplifier B, which swings rail-to-rail.
8 OUT C output Output of amplifier C, which swings rail-to-rail.
9 -IN C input Inverting input of amplifier C; the input common-mode range extends to V- (ground).
10 +IN C input Non-inverting input of amplifier C; the input common-mode range extends to V- (ground).
11 -VS power_in Negative supply (V-), typically ground; the input common-mode range extends to this pin.
12 +IN D input Non-inverting input of amplifier D; the input common-mode range extends to V- (ground).
13 -IN D input Inverting input of amplifier D; the input common-mode range extends to V- (ground).
14 OUT D output Output of amplifier D, which swings rail-to-rail.
