LM324DT from STMicroelectronics, in a SOIC-14. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUT1 output Output of op-amp channel 1. Class-AB output stage; short-circuit current approximately 40 mA independent of VCC magnitude.
2 IN1- input Inverting input of op-amp channel 1. Input common-mode voltage range includes ground (0 to VCC-1.5 V @ Tamb=25°C); typical input bias current 20 nA.
3 IN1+ input Non-inverting input of op-amp channel 1. Input common-mode range includes ground; input voltage must not exceed VCC+ or fall below VCC- by more than 0.3 V.
4 VCC+ power_in Positive supply pin, common to all four amplifiers. Single supply 3 V to 30 V or split supply +1.5 V to +15 V; absolute maximum 32 V (or ±16 V split).
5 IN2+ input Non-inverting input of op-amp channel 2. Same common-mode range and bias characteristics as channel 1.
6 IN2- input Inverting input of op-amp channel 2. Typical input bias current 20 nA, input offset current 2 nA.
7 OUT2 output Output of op-amp channel 2. Internally frequency-compensated; 1.3 MHz typical gain bandwidth product.
8 OUT3 output Output of op-amp channel 3. Class-AB output; typical short-circuit current 40 mA.
9 IN3- input Inverting input of op-amp channel 3.
10 IN3+ input Non-inverting input of op-amp channel 3.
11 VCC- power_in Negative supply / ground pin, common to all four amplifiers. Tied to GND for single-supply operation or to the negative rail for split-supply operation (-1.5 V to -15 V; absolute max -16 V).
12 IN4+ input Non-inverting input of op-amp channel 4.
13 IN4- input Inverting input of op-amp channel 4.
14 OUT4 output Output of op-amp channel 4. Class-AB output stage with internal frequency compensation.
