CBM8628AST5

Corebai Microelectronics · Precision Op Amps · SOT-23-5

CBM8628AST5 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; the datasheet gives the output drive as ±30 mA typical output current at 5 V supply and short-circuit current limit of ±25 to ±50 mA.
2 V- power_in Negative power supply pin; the part runs from a 2.7 V to 5 V single supply (or ±1.35 V to ±2.5 V dual supply) with an absolute maximum supply voltage of 6 V.
3 +IN input Non-inverting input; the input voltage range extends from V- to V+ (0 V to 5 V at 5 V supply, 0 V to 2.7 V at 2.7 V supply), and differential input voltage is rated at ±5 V.
4 -IN input Inverting input; the input voltage must stay within GND-0.3 V to VS+0.3 V per the absolute maximum ratings, and differential input voltage is rated at ±5 V.
5 V+ power_in Positive power supply pin; the part operates from 2.7 V to 5 V single supply with an absolute maximum supply voltage of 6 V.
