LOW POWER LOW OFFSET VOLTAGE DUAL COMPARATORS

Diodes Incorporated. 

Features

AP393

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: 25nA

• Low input offset current: ±5nA

• Maximum offset voltage: ±3mV

• 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

• SOP-8L, PDIP-8L package

• SOP-8L: Available in “Green” Molding Compound (No

Br, Sb) (Note 1)

• Lead Free Finish/RoHS Compliant for Lead Free and

“Green” Products (Note 2)

The AP393 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.

Application areas include limit comparators, simple analog to

digital converters; pulse, squarewave and time delay generators;

wide range VCO; MOS clock timers; multivibrators and high

voltage digital logic gates. The AP393 is designed to directly

interface with TTL and CMOS. When operated from both plus

and minus power supplies, the AP393 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
