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 1. Push-pull class-AB output; short-circuit protected (~20 mA typical short-circuit current). VOH reaches VCC+ - 1.5 V (VCC+ = 5 V, RL = 2 kΩ) up to VCC+ - 3 V approx. |+| 2 | IN1- | input | Inverting input of op-amp 1. High-impedance PNP input; input bias current ~20 nA typ (150 nA max at 25 °C). Common-mode range includes the negative rail down to VCC-. |+| 3 | IN1+ | input | Non-inverting input of op-amp 1. High-impedance PNP input; common-mode range extends from VCC- (negative rail) to (VCC+) - 1.5 V. |+| 4 | VCC+ | power_in | Positive supply rail, shared by all four op-amps. Operating range 3 V to 30 V single-supply (or ±1.5 V to ±15 V split); absolute maximum ±16 to 32 V. Total quiescent current ~0.7 mA (VCC+ = 5 V) to 1.5 mA (VCC+ = 30 V) with no load. |+| 5 | IN2+ | input | Non-inverting input of op-amp 2. Same characteristics as other non-inverting inputs; common-mode range includes VCC-. |+| 6 | IN2- | input | Inverting input of op-amp 2. Input bias current ~20 nA typ. |+| 7 | OUT2 | output | Output of op-amp 2. Class-AB output stage, short-circuit protected, sinks ~20 mA typ, sources ~40 mA typ. |+| 8 | OUT3 | output | Output of op-amp 3. Class-AB output stage, short-circuit protected. |+| 9 | IN3- | input | Inverting input of op-amp 3. |+| 10 | IN3+ | input | Non-inverting input of op-amp 3. |+| 11 | VCC- | power_in | Negative supply / ground. Typically tied to GND in single-supply operation, or to the negative rail in split-supply operation. Common-mode input range includes this rail. |+| 12 | IN4+ | input | Non-inverting input of op-amp 4. |+| 13 | IN4- | input | Inverting input of op-amp 4. |+| 14 | OUT4 | output | Output of op-amp 4. Class-AB output stage, short-circuit protected. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | STMicroelectronics |+| Package | SOIC-14 |+| Category | Op-amp/Cmp |+| Pins | 14 |++## Ordering variants++- `LM2902DTD`+- `LM2902DTDT`+- `LM2902DTYDT`+- `LM2902DTPT`+- `LM2902DTYPT`+- `LM2902DTQ4T`+- `LM2902DTYQ5T`++## CAD (KiCad official)++- Symbol: `LM2902DT`+- 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/lm2902dt.pdf) (22 pp, sha256 `67496a5ef2610b87`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
