LM224PT

STMicroelectronics · Operational Amplifier · TSSOP-14

LM224PT from STMicroelectronics, in a TSSOP-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; typical short-circuit output current ~40 mA independent of VCC. Output swings from VCC- (ground in single-supply operation) to within ~1.5 V of VCC+.
2 IN1- input Inverting input of op-amp channel 1. Typical input bias current 20 nA, input offset current 2 nA, offset voltage 5 mV max. Differential input voltage rating ±32 V.
3 IN1+ input Non-inverting input of op-amp channel 1. Common-mode input range includes ground: 0 V to VCC-1.5 V at 25 °C (0 V to VCC-2 V over temperature).
4 VCC+ power_in Positive supply rail. Single-supply operation: 3 V to 30 V referenced to VCC- = GND. Split-supply operation: +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 electrical characteristics as IN1+.
6 IN2- input Inverting input of op-amp channel 2. Same electrical characteristics as IN1-.
7 OUT2 output Output of op-amp channel 2. Same electrical characteristics as OUT1.
8 OUT3 output Output of op-amp channel 3. Same electrical characteristics as OUT1.
9 IN3- input Inverting input of op-amp channel 3. Same electrical characteristics as IN1-.
10 IN3+ input Non-inverting input of op-amp channel 3. Same electrical characteristics as IN1+.
11 VCC- power_in Negative supply rail / ground. Tied to GND for single-supply operation, or to a negative rail (-1.5 V to -15 V) for split-supply operation.
12 IN4+ input Non-inverting input of op-amp channel 4. Same electrical characteristics as IN1+.
13 IN4- input Inverting input of op-amp channel 4. Same electrical characteristics as IN1-.
14 OUT4 output Output of op-amp channel 4. Same electrical characteristics as OUT1.

CAD (KiCad official)

  • Symbol: LM224PT
  • Footprint: Package_SO:TSSOP-14_4.4x5mm_P0.65mm
  • 3D model: TSSOP-14 (KiCad packages3D, STEP)
  • 3D model files: lm224pt-etched.step / lm224pt-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm224pt.step / lm224pt.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
lm224pt.step 194 KB You want the bare part, or you mark your own boards.
lm224pt-etched.step 1.6 MB You want the part with LM224PT already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 430 faces against 237 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
