Rail-to-rail output stage; typical short-circuit current 40 mA. VOH ≈ (V+)-2 mV with RL=100 kΩ to GND. |+| 2 | INA- | input | Inverting input of amplifier channel A. High-impedance CMOS input; typical input bias current 50 pA, offset current 10 pA. Diode-clamped to the supply rails; limit input current to ±10 mA. |+| 3 | INA+ | input | Non-inverting input of amplifier channel A. Rail-to-rail input common-mode range from (V-)-0.1 V to (V+)+0.1 V. Diode-clamped to the supply rails. |+| 4 | VSS | power_in | Negative supply / ground pin (V-). Referenced to V+ for a total supply of +2.5 V to +5.5 V (7.0 V absolute max). |+| 5 | INB+ | input | Non-inverting input of amplifier channel B. Rail-to-rail input common-mode range from (V-)-0.1 V to (V+)+0.1 V. Diode-clamped to the supply rails. |+| 6 | INB- | input | Inverting input of amplifier channel B. High-impedance CMOS input; typical input bias current 50 pA, offset current 10 pA. Diode-clamped to the supply rails; limit input current to ±10 mA. |+| 7 | OUTB | output | Output of amplifier channel B. Rail-to-rail output stage; typical short-circuit current 40 mA. VOH ≈ (V+)-2 mV with RL=100 kΩ to GND. |+| 8 | VDD | power_in | Positive supply pin (V+). +2.5 V to +5.5 V single-supply, or split ±1.25 V to ±2.75 V. Absolute max supply 7.0 V. Decouple to VSS with a local ceramic capacitor. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Corebai Microelectronics |+| Package | MSOP-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `CBM8539AMS8`+- `CBM8539AMS8SOP8`++## CAD (KiCad official)++- Symbol: `CBM8539AMS8`+- Footprint: `Package_SO:MSOP-8_3x3mm_P0.65mm`+- 3D model: MSOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Corebai Microelectronics datasheet](docs/cbm8539ams8-datasheet.pdf) (14 pp, sha256 `06a1ac3ced5de972`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
