Rail-to-rail voltage swing; typical swing within 30 mV of rails into 150Ω, 8 mV into >1kΩ. Output current is 130 mA typ (100 mA min). |+| 2 | VSS | power_in | Negative supply / ground rail. Single-supply operation: connect to GND. Dual-supply operation: -1.25V to -2.75V. Bypass to ground with 0.1 µF ceramic capacitor when using dual supply. |+| 3 | IN+ | input | Non-inverting analog input. Input common-mode range -0.2 V to +3.8 V (Vs = 5 V). Input bias current 1 pA typ, input offset current 2 pA typ. Absolute max: Vss-0.5V to VDD+0.5V. |+| 4 | IN- | input | Inverting analog input. Input common-mode range -0.2 V to +3.8 V (Vs = 5 V). Input bias current 1 pA typ. Absolute max: Vss-0.5V to VDD+0.5V. |+| 5 | VDD | power_in | Positive supply. Single-supply operation 2.5 V to 5.5 V; dual supply ±1.25 V to ±2.75 V. Quiescent current 2.8 mA typ per amplifier. Bypass to ground with 0.1 µF ceramic capacitor placed close to pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Corebai Microelectronics |+| Package | SOT-23-5 |+| Category | Op-amp/Cmp |+| Pins | 5 |++## Ordering variants++Same part, different packaging or reel option.++- `CBM8051AST5`+- `CBM8051AC5`+- `CBM8051NST6`+- `CBM8051NC6`+- `CBM8052AS8`+- `CBM8052AMS8`+- `CBM8052NMS10`+- `CBM8054AS14`+- `CBM8054ATS14`++## CAD (KiCad official)++- Symbol: `CBM8051AST5`+- 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:** [Corebai Microelectronics datasheet](docs/cbm8051ast5-datasheet.pdf) (22 pp, sha256 `b126c112f37afcf8`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
