â 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 supply
Voltage that is +1.8V to ï¼5.5V(single supply) and
low supply current, extremely low input bias current.
