CBM8655AS8

Corebai Microelectronics · Precision OpAmps · SOP-8

CBM8655AS8 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 NC unconnected No connect; the datasheet marks this pin NC = NO CONNECT.
2 -IN input Inverting input of the rail-to-rail CMOS amplifier; input voltage range is 0 V to 5 V at VS = 5 V and must stay within VSS-0.3 V to VDD+0.3 V.
3 +IN input Non-inverting input of the rail-to-rail CMOS amplifier; input voltage range is 0 V to 5 V at VS = 5 V and must stay within VSS-0.3 V to VDD+0.3 V.
4 V- power_in Negative supply pin, which is ground in single-supply operation; the datasheet recommends a 0.1 µF bypass capacitor close to the package.
5 NC unconnected No connect; the datasheet marks this pin NC = NO CONNECT.
6 OUT output Rail-to-rail amplifier output with ±220 mA output current at VS = 5 V, indefinite short-circuit duration to GND and capacitive load drive up to 500 pF.
7 V+ power_in Positive supply pin for 2.7 V to 5.5 V operation with an absolute maximum supply voltage of 6 V, bypassed with 0.1 µF and 4.7 µF capacitors.
8 NC unconnected No connect; the datasheet marks this pin NC = NO CONNECT.

CAD (KiCad official)

  • Symbol: CBM8655AS8
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: cbm8655as8-etched.step / cbm8655as8-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cbm8655as8.step / cbm8655as8.glb are the bare package body.
