CBM8539AMS8

Corebai Microelectronics · Precision OpAmps · MSOP-8

CBM8539AMS8 from Corebai Microelectronics, in a MSOP-8. 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 OUTA output Output of amplifier channel A. 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.

  • 3D model files: cbm8539ams8-etched.step / cbm8539ams8-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cbm8539ams8.step / cbm8539ams8.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Corebai Microelectronics datasheet (14 pp, sha256 06a1ac3ced5de972, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
