UTC TS391/A/B
LINEAR INTEGRATED CIRCUIT
LOW POWER SINGLE VOLTAGE
COMPARATOR
DESCRIPTION
The UTC TS391/A/B consist of a low power voltage
comparator designed specifically to operate from a single
supply over a wide range of voltages. Operation from split
power supplies is also possible.
This comparator also a unique characteristic in that the
input common-mode voltage range includes ground even
though operated from a single power supply voltage.
