LOW POWER LOW OFFSET VOLTAGE DUAL COMPARATORS

Diodes Incorporated. 

Features

AP393A

LOW POWER LOW OFFSET VOLTAGE DUAL

COMPARATORS

General Description

• Wide supply

Voltage range: 2.0V to 36V

Single or dual supplies: ±1.0V to ±18V

• Very low supply current drain (0.4mA) – independent of

supply voltage

• Low input biasing current: 150nA

• Low input offset current: ±70nA

• Low input offset voltage: ±4mV

• Input common-mode voltage range includes ground

• Differential input voltage range equal to the power

supply voltage

• Low output saturation voltage: 250mV at 4mA

• Output voltage compatible with TTL, DTL, ECL, MOS

and CMOS logic systems

• MSOP-8L and SOP-8L: Available in “Green” Molding

Compound (No Br, Sb)

• Lead Free Finish/ RoHS Compliant (Note 1)

The AP393A consists of two independent precision voltage

comparators with an offset voltage specification as low as

8.0mV 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.

Application areas include limit comparators, simple analog to

digital converters; pulse, square wave and time delay generators;

wide range VCO; MOS clock timers; multivibrators and high

voltage digital logic gates. The AP393A is designed to directly

interface with TTL and CMOS. When operated from both plus

and minus power supplies, the AP393A will directly interface with

MOS logic where their low power drain is a distinct advantage

over standard comparators.

Applications

• High precision comparators

• Reduced VOS drift over temperature

• Eliminates need for dual supplies

• Allows sensing near ground

• Compatible with all forms of logic

• Power drain suitable for battery operation
