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 limited to ~40 mA. Do not short to VCC when VCC > 15 V (destructive dissipation possible). |+| 2 | IN1- | input | Inverting input of op-amp channel 1. Typical input bias current 20 nA, input offset current 2 nA. Do not drive below -0.3 V (input parasitic NPN action). |+| 3 | IN1+ | input | Non-inverting input of op-amp channel 1. Common-mode input range includes ground; upper limit is VCC - 1.5 V. |+| 4 | VCC+ | power_in | Positive supply rail. Single-supply operation 3 V to 30 V, or split-supply +1.5 V to +15 V. Absolute maximum ±16 V (single) or 32 V (single-supply). Total supply current typically 375 μA per amplifier. |+| 5 | IN2+ | input | Non-inverting input of op-amp channel 2. Common-mode input range includes ground. |+| 6 | IN2- | input | Inverting input of op-amp channel 2. Typical input bias current 20 nA. |+| 7 | OUT2 | output | Output of op-amp channel 2. Class-AB output stage; short-circuit current limited to ~40 mA. |+| 8 | OUT3 | output | Output of op-amp channel 3. Class-AB output stage; short-circuit current limited to ~40 mA. |+| 9 | IN3- | input | Inverting input of op-amp channel 3. Typical input bias current 20 nA. |+| 10 | IN3+ | input | Non-inverting input of op-amp channel 3. Common-mode input range includes ground. |+| 11 | VCC- | power_in | Negative supply rail / ground. Tie to GND for single-supply operation, or to negative rail (down to -15 V) for split-supply operation. |+| 12 | IN4+ | input | Non-inverting input of op-amp channel 4. Common-mode input range includes ground. |+| 13 | IN4- | input | Inverting input of op-amp channel 4. Typical input bias current 20 nA. |+| 14 | OUT4 | output | Output of op-amp channel 4. Class-AB output stage; short-circuit current limited to ~40 mA. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | STMicroelectronics |+| Package | SOIC-14 |+| Category | Op-amp/Cmp |+| Pins | 14 |++## Ordering variants++- `LM224ADT`+- `LM224ADTLM224DT`+- `LM224ADTLM224WDT`+- `LM224ADTLM124DT`+- `LM224ADTLM224APT`+- `LM224ADTLM224PT`+- `LM224ADTLM224WPT`+- `LM224ADTLM324APT`+- `LM224ADTLM324PT`+- `LM224ADTLM324WPT`+- `LM224ADTLM324AWPT`+- `LM224ADTLM224QT`+- `LM224ADTLM324QT`++## CAD (KiCad official)++- Symbol: `LM224ADT`+- Footprint: `Package_SO:SOIC-14_3.9x8.7mm_P1.27mm`+- 3D model: SOIC-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/lm224adt.pdf) (21 pp, sha256 `7d935f64f066d5e4`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
