LM193/LM293/LM393/LM2903

Low Power Low Offset Voltage Dual Comparators

General Description

Advantages

n High precision comparators

The LM193 series consists of two independent precision

voltage comparators with an offset voltage specification as

low as 2.0 mV max for two comparators which were de-

signed 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 characteris-

tic in that the input common-mode voltage range includes

ground, even though operated from a single power supply

voltage.

n Reduced V_OSdrift over temperature

n Eliminates need for dual supplies

n Allows sensing near ground

n Compatible with all forms of logic

n Power drain suitable for battery operation

Features

n Wide supply

— Voltage range:

2.0V to 36V

— Single or dual supplies:

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

of supply voltage

n Low input biasing current:

n Low input offset current:

n Maximum offset voltage:

n Input common-mode voltage range includes ground

n Differential input voltage range equal to the power

supply voltage

1.0V to 18V

Application areas include limit comparators, simple analog to

digital converters; pulse, squarewave and time delay gen-

erators; wide range VCO; MOS clock timers; multivibrators

and high voltage digital logic gates. The LM193 series was

designed to directly interface with TTL and CMOS. When

operated from both plus and minus power supplies, the

LM193 series will directly interface with MOS logic where

their low power drain is a distinct advantage over standard

comparators.

The LM393 and LM2903 parts are available in National’s

innovative thin micro SMD package with 8 (12 mil) large

bumps.

n Low output saturation voltage,:
