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.

°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.
