MINI ANALOG SERIES
S-892XXA Series
CMOS SINGLE COMPARATOR
The mini-analog series mounts a general purpose analog circuit
within a small package.
The S-892XXA Series is a CMOS type single comparator that can be
driven by lower voltage with lower consumption current than former
bipolar comparator. This makes it the optimum solution for small
battery powered portable equipment.
