CBM8051NST6

Corebai Microelectronics · Operational Amplifier · SOT-23-6

CBM8051NST6 from Corebai Microelectronics, in a SOT-23-6. 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 at least 84 mA (130 mA typ) of output current.
2 VSS power_in Negative supply, or ground in single-supply operation.
3 IN+ input Non-inverting amplifier input, with a common-mode range of -0.2 V to +3.8 V typical.
4 IN- input Inverting amplifier input.
5 Disable input Power-down control input: below 0.8 V max disables the amplifier, above 2 V min enables it, and supply current in disable is reduced to about 75 µA.
6 VDD power_in Positive supply of 2.5 V to 5.5 V, bypassed with a 0.1 µF ceramic capacitor.
