TS391_06 Datasheet, PDF (1/7 Pages) STMicroelectronics – Low Power Single Voltage Comparator

TS391
Low Power Single Voltage Comparator
■ Wide single supply voltage range or dual
supplies +2V to +34V or ±1V to ±17V
■ Very low supply current (0.2mA) independent
of supply voltage (1mW/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
■ TTL, DTL, ECL, CMOS compatible outputs
Description
These devices 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 has a unique characteristic
in that the input common-mode voltage range
includes ground even though operated from a
single power supply voltage.
