Corebai Microelectronics · Operational Amplifier · SOIC-8

CBMV358AS8 from Corebai Microelectronics, in a SOIC-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, rail-to-rail.
2 -IN A input Amplifier A inverting input, rail-to-rail, common-mode range -0.1V to +5.6V at Vs = 5.5V.
3 +IN A input Amplifier A non-inverting input, rail-to-rail, common-mode range -0.1V to +5.6V at Vs = 5.5V.
4 V- power_in Negative supply, or ground in single-supply operation; supply range V+ to V- is 2.5V to 5.5V (7.0V absolute max).
5 +IN B input Amplifier B non-inverting input, rail-to-rail, common-mode range -0.1V to +5.6V at Vs = 5.5V.
6 -IN B input Amplifier B inverting input, rail-to-rail, common-mode range -0.1V to +5.6V at Vs = 5.5V.
7 OUT B output Amplifier B output, rail-to-rail.
8 V+ power_in Positive supply, 2.5V to 5.5V (7.0V absolute max); place a 0.1uF capacitor closely across the supply pins.
