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. Leave floating or tie to a DC potential; not bonded to die. |+| 2 | -IN | input | Inverting analog input of the op-amp. Rail-to-rail input; common-mode range -0.1V to +5.6V with Vs=5.5V. Input bias current 1pA typ. |+| 3 | +IN | input | Non-inverting analog input of the op-amp. Rail-to-rail input; common-mode range -0.1V to +5.6V with Vs=5.5V. Input bias current 1pA typ. |+| 4 | V- | power_in | Negative supply / ground rail. Tie to GND for single-supply operation or to the negative rail for split supplies. Supply range 2.5V to 5.5V measured V+ to V-; absolute max 7.0V. |+| 5 | NC | unconnected | No internal connection. Leave floating or tie to a DC potential; not bonded to die. |+| 6 | OUT | output | Op-amp output. Rail-to-rail swing (typically within 8mV of rails at 10k load, 25mV at 2k load). Short-circuit current 55mA typ. |+| 7 | V+ | power_in | Positive supply. Operating range 2.5V to 5.5V (V+ to V-); absolute max 7.0V. Bypass with 0.1uF close to the pin. |+| 8 | NC | unconnected | No internal connection. Leave floating or tie to a DC potential; not bonded to die. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Corebai Microelectronics |+| Package | SOP-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `CBM8541AS8`++## CAD (KiCad official)++- Symbol: `CBM8541AS8`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Corebai Microelectronics datasheet](docs/cbm8541as8-datasheet.pdf) (21 pp, sha256 `991716a0c33f434a`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
