• 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

• SOT25 and SOT25R: Available in “Green” Molding

Compound (No Br, Sb)

• Lead Free Finish/ RoHS Compliant (Note 1)

The AP331A is a precision voltage comparators with an offset

voltage specification as low as 8.0 mV max for comparator 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. The

comparator 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 AP331A is designed to directly

interface with TTL and CMOS. When operated from both plus

and minus power supplies, the AP331A will directly interface with

MOS logic where their low power drain is a distinct advantage

over standard comparators.

• High precision comparators

• Reduced V

drift over temperature

• Eliminates need for dual supplies

• Allows sensing near ground

• Compatible with all forms of logic

• Power drain suitable for battery operation
