  • This device consists of four independent precision voltage comparators, which are 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 in that the input common-mode voltage range includes the negative rail even though operated from a single power supply voltage.

    Key Features

    • Wide single supply voltage range or dual supplies for all devices: +2 V to +36 V or ±1 V to ±18 V
    • Very low supply current (1.1 mA) independent of supply voltage (1.4 mW/comparator at +5 V)
    • Low input bias current: 25 nA typ.
    • Low input offset current: ±5 nA typ.
    • Input common-mode voltage range includes negative rail
    • Low output saturation voltage:250 mV typ. (IO= 4 mA)
    • Differential input voltage range equal to the supply voltage
    • TTL, DTL, ECL, MOS, CMOS compatible outputs
