LM193/LM293/LM393/LM2903 Low Power Low Offset Voltage Dual Comparators

Check for Samples: LM193-N, LM2903-N, LM293-N, LM393-N

FEATURES

DESCRIPTION

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 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.

•

Wide Supply

–

Voltage Range: 2.0V to 36V

Single or Dual Supplies: ±1.0V to ±18V

•

Very Low Supply Current Drain (0.4 mA) —

Independent of Supply Voltage

•

Low Input Biasing Current: 25 nA

Low Input Offset Current: ±5 nA

Maximum Offset voltage: ±3 mV

Input Common-Mode Voltage Range Includes

Ground

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 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.

•

Differential Input Voltage Range Equal to the

Power Supply Voltage

Low Output Saturation Voltage: 250 mV at 4

Output Voltage Compatible with TTL, DTL,

ECL, MOS and CMOS logic systems

Available in the 8-Bump (12 mil) DSBGA

Package

See AN-1112 (SNVA009) for DSBGA

Considerations

The LM393 and LM2903 parts are available in TI’s

innovative thin DSBGA package with 8 (12 mil) large

bumps.

ADVANTAGES

•

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
