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 | Op-amp 1 output. Class-AB output stage with internal short-circuit protection; typical short-circuit current ±24 mA. VOH ≈ VCC-1.5 V, VOL near VEE. |+| 2 | 1IN- | input | Op-amp 1 inverting input. Typical input bias current 50 nA, input offset current 10 nA. Differential input voltage rating ±36 V. |+| 3 | 1IN+ | input | Op-amp 1 non-inverting input. Common-mode input voltage range extends from VEE to VCC-1.5 V (single-supply rail-to-rail on the negative rail). |+| 4 | VEE | power_in | Negative supply (or GND for single-supply operation). Range: 0 V (single-supply) or down to -18 V (dual-supply). |+| 5 | 2IN+ | input | Op-amp 2 non-inverting input. Common-mode input voltage range extends from VEE to VCC-1.5 V. |+| 6 | 2IN- | input | Op-amp 2 inverting input. Typical input bias current 50 nA, input offset current 10 nA. Differential input voltage rating ±36 V. |+| 7 | 2OUT | output | Op-amp 2 output. Class-AB output stage with internal short-circuit protection; typical short-circuit current ±24 mA. |+| 8 | VCC | power_in | Positive supply. Single-supply range 3 V to 36 V; dual-supply up to +18 V. Typical quiescent current 0.5 mA at VCC=5 V, 0.8 mA at VCC=36 V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HGSEMI |+| Package | MSOP-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `LM2904MMMM/TR`+- `LM2904MMN`+- `LM2904MMM/TR`+- `LM2904MMDQ2/TR`+- `LM2904MMDQ3/TR`++## CAD (KiCad official)++- Symbol: `LM2904MM`+- Footprint: `Package_SO:MSOP-8_3x3mm_P0.65mm`+- 3D model: MSOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [HGSEMI datasheet](docs/lm2904mm-datasheet.pdf) (10 pp, sha256 `25a7f8f07393d110`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
