LM2903W

LM2903W Low-power, dual-voltage comparator D SO-8 (Plastic micropackage) P TSSOP8 (Thin shrink small outline package) S MiniSO8 Pin connections (top view) 1 - Output 1 2 - Inverting input 1 3 - Non-inverting input 1 4 - VCC5 - Non-inverting input 2 6 - Inverting input 2 7 - Output 2 8 - VCC+ Datasheet - production data 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. (IO = 4 mA) Differential input voltage range equal to the supply voltage TTL, DTL, ECL, MOS, CMOS compatible outputs ESD internal protection: 2 kV Description This device consists of two independent lowpower 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 VCC+ or VCCmagnitudes.
