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.
FEATURES
*Wide single supply voltage range or dual supplies +2V to
*+34V or ±1V to ±18V
*Very low supply current (0.2mA) independent of supply
voltage (1 mW /comparator at +5V)
*Low input bias current: 25nA typ.
*Low input offset current: ±5nA typ.
*Low input offset voltage: ±1mV typ
*Input common-mode voltage range includes ground.
*Low output saturation voltage: 250mV typ.(Io=4mA).
*Differential input voltage range equal to the supply
*voltage.
