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. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | STMicroelectronics |+| Package | TSSOP-14 |+| Category | Op-amp/Cmp |+| Pins | 14 |++## Ordering variants++- `LM224PTPT`+- `LM224PTAPT`+- `LM224PTWPT`+- `LM224PTDT`+- `LM224PTADT`+- `LM224PTWDT`+- `LM224PTQT`++## CAD (KiCad official)++- Symbol: `LM224PT`+- Footprint: `Package_SO:TSSOP-14_4.4x5mm_P0.65mm`+- 3D model: TSSOP-14 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [STMicroelectronics datasheet](https://www.st.com/resource/en/datasheet/lm224pt.pdf) (22 pp, sha256 `c1aa97669d6ca9c8`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
