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 | +IN | input | Non-inverting analog input. Common-mode input voltage range extends from V- - 0.1V to V+ + 0.1V (rail-to-rail input) with Vs = 5.5V. Input bias current typ. 1pA. |+| 2 | V- | power_in | Negative supply / ground rail. Total supply range V+ to V- = 2.5V to 5.5V (7.0V absolute max). Tie to GND for single-supply operation. |+| 3 | -IN | input | Inverting analog input. Rail-to-rail input range; inputs are diode-clamped to the supply rails and must be current-limited to <=10mA if driven >0.5V beyond either rail. |+| 4 | OUT | output | Rail-to-rail amplifier output. Output swing to within 8mV of the rails with 10k load, 25mV with 2k load. Short-circuit output current typ. 55mA. Slew rate 0.5V/us. |+| 5 | V+ | power_in | Positive supply rail, +2.5V to +5.5V (7.0V absolute max V+ to V-). Quiescent current 58uA typ, 80uA max. Decouple locally with a 0.1uF ceramic capacitor to V-. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Jiangsu RUNIC Tech |+| Package | SOT-23-5 |+| Category | Op-amp/Cmp |+| Pins | 5 |++## Ordering variants++- `RS6331BXF`+- `RS6331BXFRS6331XF`+- `RS6331BXFRS6331XK`+- `RS6331BXFRS6331XM`++## CAD (KiCad official)++- Symbol: `RS6331BXF`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Jiangsu RUNIC Tech datasheet](docs/rs6331bxf-datasheet.pdf) (18 pp, sha256 `b116c9f04b5bdc78`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
