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 | OUT | output | Amplifier output. Rail-to-rail output stage; short-circuit current typically 50 mA. |+| 2 | V- | power_in | Negative supply pin. Connect to ground for single-supply operation or to the negative rail for dual-supply operation. Total supply (V+ minus V-) must be 2.7 V to 5.5 V (7.0 V absolute maximum). |+| 3 | +IN | input | Non-inverting input. Rail-to-rail input common-mode range from (V-)-0.1 V to (V+)+0.1 V. Input bias current 50 pA typical; input terminals are diode-clamped to the supplies. |+| 4 | -IN | input | Inverting input. Rail-to-rail input common-mode range from (V-)-0.1 V to (V+)+0.1 V. Input bias current 50 pA typical; input terminals are diode-clamped to the supplies. |+| 5 | V+ | power_in | Positive supply pin. Operating range +2.7 V to +5.5 V referenced to V- (7.0 V absolute maximum). Place a 0.1 uF decoupling capacitor close to the supply pins. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Jiangsu RUNIC Tech |+| Package | SOT-23-5 |+| Category | Op-amp/Cmp |+| Pins | 5 |++## Ordering variants++- `RS8551XFXF`+- `RS8551XFXK`+- `RS8551XFXM`++## CAD (KiCad official)++- Symbol: `RS8551XF`+- 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/rs8551xf-datasheet.pdf) (14 pp, sha256 `6237f5e7f699705d`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
