Overview
SOT23-5 DFN8 2x2 Maturity status link TS391, TS391A TS391, TS391A Datasheet Low-power single voltage comparator Features • Wide single supply voltage range or dual supplies 2 V to 36 V or ± 1 V to ± 18 V • Very low supply current (0.
2 mA) independent of supply voltage (1 mW / comparator at 5 V) • Low input bias current: 25 nA typ.
• Low input offset current: ± 5 nA typ.
• Low input offset voltage: ± 2 mV max.
for TS391A • Input common-mode voltage range includes ground • Low output saturation voltage: 250 mV typ.
(Io = 4 mA) • 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.
These comparators also have a unique characteristic where the input common-mode voltage range includes ground, even though operated from a single power supply voltage.
