LM224M

HGSEMI · Operational Amplifier · SOIC-14

LM224M from HGSEMI, 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 (AMPL #1). Output swing 0 to Vcc-1.5 V; short-circuit output current typ. 35 mA.
2 IN1- input Inverting input of op-amp channel 1. Input common-mode range 0 V to Vcc-1.5 V; input bias current typ. 45 nA.
3 IN1+ input Non-inverting input of op-amp channel 1. Input common-mode range 0 V to Vcc-1.5 V. (Datasheet table labels this row 'IN+ (#2)' but description reads '正向输入 1' - treated as channel-1 non-inverting input.)
4 Vcc power_in Positive supply. Single supply 3 V to 32 V, or ±1.5 V to ±16 V for split supply. Absolute maximum 32 V.
5 IN2+ input Non-inverting input of op-amp channel 2.
6 IN2- input Inverting input of op-amp channel 2.
7 OUT2 output Output of op-amp channel 2.
8 OUT3 output Output of op-amp channel 3.
9 IN3- input Inverting input of op-amp channel 3.
10 IN3+ input Non-inverting input of op-amp channel 3.
11 GND power_in Ground / negative supply return. For split-supply operation this is Vee (−1.5 V to −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.
