Product Summary

The LM2903DT is a low power dual voltage comparator. The LM2903DT 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 LM2903DT also has a unique characteristic in that the input common-mode voltage range includes ground even though operated from a single power supply voltage.

Parametrics

LM2903DT absolute maximum ratings: (1)VCC Supply Voltage: ±18 to 36 V; (2)VID Differential Input Voltage: ±36 V; (3)VI Input Voltage: -0.3 to +36 V; (4)Output Short-circuit to Ground: Infinite; (5)Pd Power Dissipation: 625 mW; (6)TJunction Junction Temperature: +150℃; (7)Tstg Storage Temperature Range: -65 to +150℃.

Features

LM2903DT features: (1)wide single supply voltage range or dual supplies +2V to +36V or ±1V to ±18V; (2)very low supply current (0.4mA) independent of supply voltage (1mW/comparator at +5V); (3)low input bias current: 25nA TYP; (4)low input offset current: ±5nA TYP; (5)input common-mode voltage range includes ground; (6)low output saturation voltage: 250mV TYP. (IO = 4mA); (7)differential input voltage range equal to the supply voltage; (8)TTL, DTL, ECL, MOS, CMOS compatible outputs.
