HA17903, HA17393 Series
Dual Comparator
Description
HA17903 and HA17393 are comparators designed for car use and control system use.
They provide wide voltage range with single power source, and the change of supply current is small,
because it is independent of the supply voltage. They can be widely applied, such as limit comparator,
simple analog/digital converter, pulse/square wave/time delay generator, wide range VCO, MOS clock
timer, multivibrator, high voltage logic gate, etc.
Features
•
Wide supply voltage: 2 to 36V
•
Very low supply current: 0.8mA
•
•
•
•
•
Small input bias: 25nA
Small input offset current: 3nA
Small input offset voltage: 2mV
Common mode input voltage range including ground.
Small output saturation voltage: 1mV (5µA)
70mV (1mA)
•
Output voltage is compatible with CMOS logic system.

1. These are the allowable values up to Ta = 55
°C.
Derate by 8.3mW/°C above that temperature.
2. These are the allowable values up to Ta = 45
°C
mounting on 30% wiring density glass epoxy
board. Derate by 7.14mW/°C above that temperature.
3. Short circuit between the output and VCC will be a cause to destory the circuit. The maximum
output current is about 20mA for any supply voltage.
