3 Description
The LM393B and LM2903B devices are the
next generation versions of the industry-standard
LM393 and LM2903 comparator family. These next
generation B-version comparators feature lower offset
voltage, higher supply voltage capability, lower supply
current, lower input bias current, lower propagation
delay, and improved 2 kV ESD performance and
input ruggedness through dedicated ESD clamps.
The LM393B and LM2903B can drop-in replace the
LM293, LM393 and LM2903, for both „A“ and „V“
grades.
All devices consist of two independent voltage
comparators that are designed to operate from a
single power supply over a wide range of voltages.
Quiescent current is independent of the supply
voltage.
