CBM8333AST5

Corebai Microelectronics · Precision OpAmps · SOT-23-5

CBM8333AST5 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, able to deliver 30 mA output current.
2 VSS power_in Negative supply or ground; for dual-supply use (±0.9V to ±2.75V) bypass with a 0.1µF ceramic capacitor.
3 IN+ input Non-inverting input with rail-to-rail range, from VSS-0.1V to VDD+0.1V, and 20 pA typical bias current.
4 IN- input Inverting input with rail-to-rail range, from VSS-0.1V to VDD+0.1V, and 20 pA typical bias current.
5 VDD power_in Positive supply, 1.8V to 5.5V single supply (absolute maximum 7.5V VDD to VSS), bypassed with a 0.1µF ceramic capacitor.
