BDM8551B

Bardeen Micro. · Operational Amplifier · SOT-23-5L

BDM8551B from Bardeen Micro., in a SOT-23-5L. 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.
2 VS- power_in Negative (lowest) power supply; supply range is 1.8 V to 5.5 V single-supply (VS+ to VS-) per the electrical characteristics, and VS+ to VS- must not exceed 10.0 V absolute maximum.
3 IN+ input Non-inverting input of the amplifier; signal input voltage must stay within VS- - 0.5 V to VS+ + 0.5 V with input current limited to ±20 mA.
4 IN- input Inverting input of the amplifier; signal input voltage must stay within VS- - 0.5 V to VS+ + 0.5 V with input current limited to ±20 mA.
5 VS+ power_in Positive (highest) power supply; must not exceed 10.0 V above VS- (absolute maximum), with operation specified from 1.8 V to 5.5 V.
