LM2903EP

Low Power Low Offset Voltage Dual Comparators

General Description

Advantages

The LM2903EP consists of two independent precision volt-

age comparators with an offset voltage specification as low

as 2.0 mV 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 indepen-

dent of the magnitude of the power supply voltage. This

comparator also has a unique characteristic in that the input

common-mode voltage range includes ground, even though

operated from a single power supply voltage.

High precision comparators

■

Reduced V_OSdrift over temperature

Eliminates need for dual supplies

Allows sensing near ground

Compatible with all forms of logic

Power drain suitable for battery operation

Features

Wide supply

■

Application areas include limit comparators, simple analog to

digital converters; pulse, squarewave and time delay gener-

ators; wide range VCO; MOS clock timers; multivibrators and

high voltage digital logic gates. The LM2903EP was designed

to directly interface with TTL and CMOS. When operated from

both plus and minus power supplies, the LM2903EP will di-

rectly interface with MOS logic where their low power drain is

a distinct advantage over standard comparators.

Voltage range:

2.0V to 36V

±1.0V to ±18V

Single or dual supplies:

Very low supply current drain (0.4 mA) — independent of

supply voltage

Low input biasing current:

Low input offset current:

Maximum offset voltage:

Input common-mode voltage range includes ground

Differential input voltage range equal to the power supply
