Product overview

Description

The LM2903B consists of two independent low-power voltage comparators designed specifically to operate from a single supply over a wide range of voltages. It is fully specified at 5 V and 36 V supply voltage operation, however operation from split power supplies is also possible.

In addition, the device has a unique characteristic in that the input common-mode voltage range includes the negative rail 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 0.5 mA typ., essentially independent of supply voltage
    • Low input bias current: 20 nA typ.
    • Low input offset current: ±5 nA typ.
    • Input common-mode voltage range includes negative rail
    • Low output saturation voltage: 250 mV typ. (Iout = 4 mA)
    • Differential input voltage range equal to the supply voltage
    • TTL, DTL, ECL, MOS, CMOS compatible outputs
    • Automotive qualification
