●Description

CMOS comparator BU7251/BU7231family and BU7252/BU7232 family are input full swing and push pull output comparator.

These ICs integrate one op-amp or two independent op-amps and phase compensation capacitor on a single chip.

The features of these ICs are low operating supplyVoltage that is +1.8V to +5.5V(single supply) and low supply current,

extremely low input bias current.
