LM324ADR-CN

ChipNobo · Operational Amplifier · SOP-14

LM324ADR-CN from ChipNobo, in a SOP-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 OUT1 output Output of amplifier 1, short-circuit protected, with output range 0 to Vcc-1.5 V.
2 IN1- input Inverting input of amplifier 1; common-mode range includes the negative supply (0 to Vcc-1.5 V).
3 IN1+ input Non-inverting input of amplifier 1; common-mode range includes the negative supply (0 to Vcc-1.5 V).
4 VCC power_in Positive supply for single-supply operation from 3.0 V to 32 V (absolute maximum 32 V).
5 IN2+ input Non-inverting input of amplifier 2; common-mode range includes the negative supply (0 to Vcc-1.5 V).
6 IN2- input Inverting input of amplifier 2; common-mode range includes the negative supply (0 to Vcc-1.5 V).
7 OUT2 output Output of amplifier 2, short-circuit protected, with output range 0 to Vcc-1.5 V.
