Corebai Microelectronics · Operational Amplifier · SOT-23-5

CBM8051AST5 from Corebai Microelectronics, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUT output Amplifier output. Rail-to-rail voltage swing; typical swing within 30 mV of rails into 150Ω, 8 mV into >1kΩ. Output current is 130 mA typ (100 mA min).
2 VSS power_in Negative supply / ground rail. Single-supply operation: connect to GND. Dual-supply operation: -1.25V to -2.75V. Bypass to ground with 0.1 µF ceramic capacitor when using dual supply.
3 IN+ input Non-inverting analog input. Input common-mode range -0.2 V to +3.8 V (Vs = 5 V). Input bias current 1 pA typ, input offset current 2 pA typ. Absolute max: Vss-0.5V to VDD+0.5V.
4 IN- input Inverting analog input. Input common-mode range -0.2 V to +3.8 V (Vs = 5 V). Input bias current 1 pA typ. Absolute max: Vss-0.5V to VDD+0.5V.
5 VDD power_in Positive supply. Single-supply operation 2.5 V to 5.5 V; dual supply ±1.25 V to ±2.75 V. Quiescent current 2.8 mA typ per amplifier. Bypass to ground with 0.1 µF ceramic capacitor placed close to pin.
