Product specification
AU2903
Low power dual voltage comparator
300
August 31, 1994
853-1636 13721
DESCRIPTION
The AU2903 consists of two independent precision voltage
comparators with an offset voltage specification as low as 2.0mV
max. for two comparators which were designed specifically to
operate from a single power supply over a wide range of voltages.
Operation from split power supplies is also possible and the low
power supply current drain is independent of the magnitude of the
power supply voltage. These comparators also have a unique
characteristic in that the input common-mode voltage range includes
ground, even though operated from a single power supply voltage.
FEATURES
Wide single supply voltage range 2.0V
DC to 36VDC or dual
supplies
±1.0VDC, to ±18VDC
Very low supply current drain (0.8mA) independent of supply
voltage (2.0mW/comparator at 5.0VDC)
Low input biasing current 25nA
Low input offset current ±5nA and offset voltage ±2mV
Input common-mode voltage range includes ground
Differential input voltage range equal to the power supply voltage
Low output 250mV at 4mA saturation voltage
Output voltage compatible with TTL, DTL, ECL, MOS and CMOS
logic systems
APPLICATIONS
