Rail-to-rail output stage; typical short-circuit current 30mA. |+| 2 | -IN_A | input | Inverting input of op-amp channel A. Input bias current typically 60pA; input common-mode range extends to V-. |+| 3 | +IN_A | input | Non-inverting input of op-amp channel A. Input common-mode voltage range includes ground (V-). |+| 4 | -VS | power_in | Negative supply rail (or GND in single-supply operation). Total supply voltage (+Vs)-(-Vs) 3V to 36V (40V absolute max). |+| 5 | +IN_B | input | Non-inverting input of op-amp channel B. Input common-mode voltage range includes ground (V-). |+| 6 | -IN_B | input | Inverting input of op-amp channel B. Input bias current typically 60pA. |+| 7 | OUT_B | output | Output of op-amp channel B. Rail-to-rail output stage; typical short-circuit current 30mA. |+| 8 | +VS | power_in | Positive supply rail. Supply range 3V to 36V (single or split). Absolute maximum total supply 40V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | 3PEAK |+| Package | SOIC-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `LM2904A-SRSR`+- `LM2904A-SRTSR`+- `LM2904A-SRVR`+- `LM2904A-SRSR (LM2902A-SR)`+- `LM2904A-SRTR (LM2902A-TR)`++## CAD (KiCad official)++- Symbol: `LM2904A-SR`+- 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:** [3PEAK datasheet](docs/lm2904a-sr-datasheet.pdf) (14 pp, sha256 `dcb73ef4df32ac65`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
