LM193-N, LM2903-N, LM293-N, LM393-N
SNOSBJ6G – OCTOBER 1999 – REVISED OCTOBER 2018
LMx93-N, LM2903-N Low-Power, Low-Offset Voltage, Dual Comparators
1 Features
3 Description
•
The LM193-N 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: 2.0 V to 36 V
– Single or Dual Supplies: ±1.0 V to ±18 V
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
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
Advantages
– High Precision Comparators
– Reduced VOS Drift Over Temperature
– Eliminates Need for Dual Supplies
– Allows Sensing Near Ground
– Compatible with All Forms of Logic
– Power Drain Suitable for Battery Operation

Battery Powered Applications
Industrial Applications
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-N series was designed to directly
interface with TTL and CMOS. When operated from
both plus and minus power supplies, the LM19-N
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 TI’s
innovative thin DSBGA package with 8 (12 mil) large
bumps.
