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.
