LM2903WH

This device consists of two independent low-power voltage comparators designed specifically to operate from a single supply over a wide range of voltages. Operation from split power supplies is also possible.

The input common-mode voltage range includes negative rail even though operated from a single power supply voltage.

All pins are protected against electrostatic discharge up to 2 kV. Consequently, the input voltages must not exceed the V_CC⁺ or V_CC^- magnitudes.

Key Features

Wide, single supply voltage range or dual supplies, 2 V to 36 V or ±1 V to ±18 V
Very low supply current (0.4 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.
Input common-mode voltage range includes negative rail
Low output saturation voltage: 250 mV typ. (I_O = 4 mA)
Differential input voltage range equal to the supply voltage
TTL, DTL, ECL, MOS, CMOS compatible outputs
ESD internal protection: 2 kV
Wide operating temperature range: -40 to 150 °C
