CBM6042AS8

Corebai Microelectronics · Operational Amplifier · SOP-8

CBM6042AS8 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 OUTA output Amplifier A output, rail-to-rail swing.
2 INA- input Amplifier A inverting input; common-mode range VSS-0.1V to VDD+0.1V.
3 INA+ input Amplifier A non-inverting input; common-mode range VSS-0.1V to VDD+0.1V.
4 VSS power_in Negative supply or ground; for dual supply, bypass with a 0.1uF ceramic capacitor.
5 INB+ input Amplifier B non-inverting input; common-mode range VSS-0.1V to VDD+0.1V.
6 INB- input Amplifier B inverting input; common-mode range VSS-0.1V to VDD+0.1V.
7 OUTB output Amplifier B output, rail-to-rail swing.
8 VDD power_in Positive supply, 1.4V to 5.5V; place a 0.1uF ceramic capacitor close to the pin.
