LND393

Dual Differential Comparators

GENERAL DESCRIPTION

FEATURES

The LND393 consists of two independent

precision voltage comparators with an offset

voltage specification as low as 2.0 mV max for

two comparators. They are specifically

designed to operate from a single power supply

over a wide range of voltages. In addition, the

comparators have the unique ability in that the

input common-mode voltage range includes

ground, while operated from a single power

supply voltage. 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.

•

Wide supply (Voltage range single

and dual supplies 5V to 30V, 2.5V to

15V)

•

Very Low supply current drain(0.8mA)

Low input biasing current(25nA)

Low input offset voltage( 5nA)

Maximum offset voltage( 5mV)

Input common-mode voltage range

includes ground

Differential input voltage range equal

to the power supply voltage

Output voltage compatible with TTL,

DTL,ECL ,MOS and CMOS logic

systems

•

Application areas include limit comparators,

simple analog to digital converters, pulse,

squarewave and time delay generators: wide

range VCO, MOS clock timers, multi-vibrators

and high voltage digital logic gates. The

LND393 was designed to directly interface with

TTL and CMOS. When the LND393 is operated

from both plus and minus power supplies, it will

directly interface with MOS logic where their low

power drain is a distinct advantage over

standard comparators.

ADVANTAGES

•

High precision comparators

Reduce V_OSdrift over temperature

Power drain suitable for battery

operation

Compatible with all forms of logic

Allows sensing near ground

Eliminates need for dual supplies
