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  
mA  
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.
