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. Class-AB output stage; output can swing from 0 V up to approximately (VCC+ - 1.5 V). Short-circuit output current is approximately 40 mA and short-circuit duration is infinite (subject to power dissipation limits). |+| 2 | In1- | input | Inverting input of op-amp #1. High-impedance input; typical input bias current 20 nA, typical input offset current 2 nA. Common-mode input range extends from VCC- (ground in single-supply operation) up to VCC+ - 1.5 V. |+| 3 | In1+ | input | Non-inverting input of op-amp #1. High-impedance input; common-mode range includes the negative supply rail (VCC-). Absolute maximum input voltage is -0.3 V to 32 V (LM2904/A) or -0.3 V to VCC+0.3 V (LM2904W/AW). |+| 4 | Vcc- | power_in | Negative supply rail (or GND in single-supply operation). Total supply voltage VCC+ to VCC- must be between 3 V and 30 V (absolute max 32 V or ±16 V). |+| 5 | In2+ | input | Non-inverting input of op-amp #2. High-impedance input; common-mode input range includes the negative supply rail. Same input specifications as In1+. |+| 6 | In2- | input | Inverting input of op-amp #2. High-impedance input; same input bias/offset specifications as In1-. |+| 7 | Out2 | output | Output of op-amp #2. Class-AB output stage; output swing 0 V to (VCC+ - 1.5 V). Short-circuit output current approximately 40 mA. |+| 8 | Vcc+ | power_in | Positive supply rail. Operating range 3 V to 30 V (single-supply) or ±1.5 V to ±16 V (dual-supply); absolute maximum 32 V or ±16 V. Very low supply current, essentially independent of supply voltage. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | STMicroelectronics |+| Package | SOIC-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `LM2904DTDT`+- `LM2904DTD`+- `LM2904DTDR`+- `LM2904DTDG4`+- `LM2904DTPT`+- `LM2904DTST`+- `LM2904DTC2T`++## CAD (KiCad official)++- Symbol: `LM2904DT`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [STMicroelectronics datasheet](https://www.st.com/resource/en/datasheet/lm2904dt.pdf) (28 pp, sha256 `f44e9d8956cbcbb3`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
