CBM8542AS8

Corebai Microelectronics · Operational Amplifier · SOP-8

CBM8542AS8 from Corebai Microelectronics, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUT A output Amplifier A output with rail-to-rail swing, within 8mV of the rail at RL=10kΩ and a short-circuit current of 55mA.
2 -IN A input Amplifier A inverting input, diode-clamped to the supply rails, with input signals more than 0.5V beyond the rails limited to 10mA.
3 +IN A input Amplifier A non-inverting input, with a common-mode range of -0.1V to 5.6V at Vs=5.5V and diode-clamped to the supply rails.
4 V- power_in Negative supply (ground in single-supply use); total supply V+ to V- is 2.5V to 5.5V, with an absolute maximum of 7.0V.
5 +IN B input Amplifier B non-inverting input, with a common-mode range of -0.1V to 5.6V at Vs=5.5V and diode-clamped to the supply rails.
6 -IN B input Amplifier B inverting input, diode-clamped to the supply rails, with input signals more than 0.5V beyond the rails limited to 10mA.
7 OUT B output Amplifier B output with rail-to-rail swing, within 8mV of the rail at RL=10kΩ and a short-circuit current of 55mA.
8 V+ power_in Positive supply, 2.5V to 5.5V with 7.0V absolute maximum between V+ and V-, and a 0.1uF capacitor placed closely across the supply pins.

CAD (KiCad official)

  • Symbol: CBM8542AS8
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: cbm8542as8-etched.step / cbm8542as8-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cbm8542as8.step / cbm8542as8.glb are the bare package body.

Provenance

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

  • Datasheet: Corebai Microelectronics datasheet (21 pp, sha256 433cd7c36cbead69, retrieved 2026-11-02, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (text+vision), consensus claude-opus-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
