LM2903WH Low-power, dual-voltage comparator Datasheet - production data S MiniSO8 (plastic micropackage) Pin connections (top view) 1 - Output 1 2 - Inverting input 1 3 - Non-inverting input 1 4 - VCC 5 - Non-inverting input 2 6 - Inverting input 2 7 - Output 2 8 - VCC+ 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 Wide operating temperature range: -40 to 150 °C Description 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 VCC+ or VCCmagnitudes.

The maximum output current is approximately 20 mA and is independent of the VCC+ magnitude. (2)Short-circuits can cause excessive heating and destructive dissipation. Values are typical and for a four-layer PCB. (3)Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a 1.5 kΩ resistor between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating. (4)Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5 Ω). This is done for all couples of connected pin combinations while the other pins are floating. (5)Charged device model: all pins and the package are charged together to the specified voltage and then discharged directly to the ground through only one pin. This is done for all pins.
