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 | NC | unconnected | No internal connection. May be left floating or tied to any potential within the absolute maximum ratings; typically left unconnected. |+| 2 | IN- | input | Inverting analog input of the op-amp. Rail-to-rail common-mode range extending 100mV beyond the supply rails (VSS-0.1V to VDD+0.1V). Very low input bias current (~20pA typical). |+| 3 | IN+ | input | Non-inverting analog input of the op-amp. Rail-to-rail common-mode range extending 100mV beyond the supply rails (VSS-0.1V to VDD+0.1V). Very low input bias current (~20pA typical). |+| 4 | VSS | power_in | Negative supply rail / ground. Total supply (VDD-VSS) range 1.8V to 5.5V (absolute max 7.5V). Bypass to VDD with a 0.1µF ceramic capacitor placed close to the device; for dual-supply operation bypass both VDD and VSS to ground separately. |+| 5 | NC | unconnected | No internal connection. May be left floating or tied to any potential within the absolute maximum ratings; typically left unconnected. |+| 6 | OUT | output | Op-amp output. Rail-to-rail output swing; typically within 5mV of the rails into >100kΩ loads and within 60mV into 10kΩ. Short-circuit current ~60mA, output current up to ~65mA. |+| 7 | VDD | power_in | Positive supply rail. Single-supply range 1.8V to 5.5V referenced to VSS (absolute max VDD-VSS = 7.5V). Place a 0.1µF ceramic bypass capacitor close to this pin. |+| 8 | NC | unconnected | No internal connection. May be left floating or tied to any potential within the absolute maximum ratings; typically left unconnected. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Corebai Microelectronics |+| Package | SOIC-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `CBM8551AS8`+- `CBM8551AS8AST5`++## CAD (KiCad official)++- Symbol: `CBM8551AS8`+- 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:** [Corebai Microelectronics datasheet](docs/cbm8551as8-datasheet.pdf) (None pp, sha256 `f2188dc09cf52931`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
