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 | 1OUT | output | Channel 1 output. Op-amp output stage capable of sourcing/sinking up to ~40mA (typ short-circuit), swinging from ~0V to VCC-1.5V. |+| 2 | 1IN- | input | Channel 1 inverting input. High-impedance input with typical input bias current of -20nA (PNP input stage sources current out of the pin). |+| 3 | 1IN+ | input | Channel 1 non-inverting input. Input common-mode voltage range includes ground (0V to VCC-1.5V); tolerates up to +36V without damage. |+| 4 | GND | power_in | Ground / negative supply. In single-supply operation this is 0V; in dual-supply operation this connects to the negative rail (down to -18V relative to VCC). |+| 5 | 2IN+ | input | Channel 2 non-inverting input. Input common-mode voltage range includes ground (0V to VCC-1.5V); tolerates up to +36V without damage. |+| 6 | 2IN- | input | Channel 2 inverting input. High-impedance input with typical input bias current of -20nA (PNP input stage sources current out of the pin). |+| 7 | 2OUT | output | Channel 2 output. Op-amp output stage capable of sourcing/sinking up to ~40mA (typ short-circuit), swinging from ~0V to VCC-1.5V. |+| 8 | VCC | power_in | Chip positive supply voltage. Single supply 3V to 36V, or positive rail of dual supply ±1.5V to ±18V. Bypass with 0.1µF ceramic close to pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes Incorporated |+| Package | SO-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `LM2904QS-13`+- `LM2904QS-13LM2904AQS-13`+- `LM2904QS-13LM2904QTH-13`+- `LM2904QS-13LM2904AQTH-13`+- `LM2904QS-13LM2904QM8-13`+- `LM2904QS-13LM2904AQM8-13`+- `LM2904QS-13LM2902QS14-13`+- `LM2904QS-13LM2902AQS14-13`+- `LM2904QS-13LM2902QT14-13`+- `LM2904QS-13LM2902AQT14-13`++## CAD (KiCad official)++- Symbol: `LM2904QS-13`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SO-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Diodes Incorporated datasheet](docs/lm2904qs-13-datasheet.pdf) (None pp, sha256 `12a3965c03721356`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
