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 | OUTA | output | Output of amplifier A. Push-pull output stage; internally short-circuit protected (Isc ≈ 40 mA typ). Output swings from VEE+VOL (~5-20 mV above VEE with RL=10 kΩ) up to VCC−1.5 V. |+| 2 | INA- | input | Inverting input of amplifier A. Low input bias current (typ −45 nA); differential input voltage range up to ±VCC. Common-mode range extends to VEE (ground). |+| 3 | INA+ | input | Non-inverting input of amplifier A. Low input bias current (typ −45 nA); common-mode input voltage range from 0 V (VEE) up to VCC−1.7 V. ESD-clamped input. |+| 4 | VEE/GND | power_in | Negative supply / ground return for both amplifiers. Tie to 0 V in single-supply operation (3.0 V ≤ VCC ≤ 32 V) or to a negative rail (down to −16 V) in split-supply operation. |+| 5 | INB+ | input | Non-inverting input of amplifier B. Low input bias current (typ −45 nA); common-mode input voltage range from 0 V (VEE) up to VCC−1.7 V. ESD-clamped input. |+| 6 | INB- | input | Inverting input of amplifier B. Low input bias current (typ −45 nA); differential input voltage range up to ±VCC. Common-mode range extends to VEE (ground). |+| 7 | OUTB | output | Output of amplifier B. Push-pull output stage; internally short-circuit protected (Isc ≈ 40 mA typ). Output swings from VEE+VOL (~5-20 mV above VEE with RL=10 kΩ) up to VCC−1.5 V. |+| 8 | VCC | power_in | Positive supply pin, common to both amplifiers. Single-supply range 3.0 V to 32 V, or +1.5 V to +16 V in split-supply mode. Total quiescent current typ 0.7 mA at VCC=5 V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | onsemi |+| Package | SOIC-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `NCV2904DR2GD`+- `NCV2904DR2GDR2G`+- `NCV2904DR2GVD`+- `NCV2904DR2GVDR2G`+- `NCV2904DR2GDG`+- `NCV2904DR2GDR2G`+- `NCV2904DR2GN`+- `NCV2904DR2GAN`+- `NCV2904DR2GVN`+- `NCV2904DR2GDMR2`+- `NCV2904DR2GDMR2G`++## CAD (KiCad official)++- Symbol: `NCV2904DR2G`+- 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:** [onsemi datasheet](https://www.onsemi.com/pdf/datasheet/ncv2904-d.pdf) (14 pp, sha256 `3a1bc4722a28615c`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
