CBM8091AST5

Corebai Microelectronics · Operational Amplifier · SOT-23-5

CBM8091AST5 from Corebai Microelectronics, in a SOT-23-5. 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 output Amplifier output with rail-to-rail swing, typically within 30mV of the supply rail with loads above 1kΩ and within 120mV with a 150Ω load.
2 VSS power_in Negative supply, which is ground in single-supply operation; the supply range from VDD to VSS is 2.5V to 5.5V.
3 IN+ input Non-inverting input, with a common-mode range of -0.2V to +3.8V typical and an absolute maximum of VSS-0.5V to VDD+0.5V.
4 IN- input Inverting input, with an absolute maximum of VSS-0.5V to VDD+0.5V.
5 VDD power_in Positive supply, specified for 2.5V to 5.5V single-supply operation, with a 0.1µF ceramic bypass capacitor placed close to the pin.
