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 | Open-collector output of comparator A. Requires an external pull-up resistor to a positive supply (typ. 1 kΩ-100 kΩ). Sinks up to 16 mA when active. |+| 2 | OUTB | output | Open-collector output of comparator B. Requires an external pull-up resistor to a positive supply. Sinks up to 16 mA when active. |+| 3 | VCC | power_in | Positive supply voltage. Single-supply operation from +2.0 V to +36 V, or split-supply ±1.0 V to ±18 V. Typical supply current 0.8 mA for both comparators. |+| 4 | IN-B | input | Inverting input of comparator B. Common-mode input voltage range includes ground (V_CC − 1.5 V max). Input bias current typ. 25 nA. |+| 5 | IN+B | input | Non-inverting input of comparator B. Common-mode input voltage range includes ground. Input offset voltage typ. 2 mV. |+| 6 | IN-A | input | Inverting input of comparator A. Common-mode input voltage range includes ground (V_CC − 1.5 V max). Input bias current typ. 25 nA. |+| 7 | IN+A | input | Non-inverting input of comparator A. Common-mode input voltage range includes ground. Input offset voltage typ. 2 mV. |+| 8 | GND | power_in | Ground / negative supply reference. Tie to 0 V for single-supply operation, or to V_EE for split-supply operation. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | onsemi |+| Package | SOIC-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `NCV2903DR2GDR2G`++## CAD (KiCad official)++- Symbol: `NCV2903DR2G`+- 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/ncv2903-d.pdf) (13 pp, sha256 `b87721993d627de6`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
