Product overview

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.

  • All 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
