Datasheet SummaryAI
# LM393B, LM2903B, LM193, LM293, LM393 and LM2903 Dual Comparators

## Features
️· New B-version with improved specifications: up to 38V rating, 2kV ESD, 0.37mV offset, 3.5nA bias, 200uA current, 1usec response.
️· Drop-in replacement for LM293, LM393, LM2903 (A & V versions).
️· Common-mode input includes ground.
️· Differential input voltage equal to maximum supply voltage (±38V).
️· Low output saturation voltage and TTL/MOS/CMOS compatible output.

## Applications
️· Vacuum robots
️· Single-phase UPS
️· Server PSUs
️· Cordless power tools
️· Wireless infrastructure
️· Appliances
️· Building/Factory automation
️· Motor drives
️· Infotainment/cluster

## Description
The LM393B/LM2903B are next-generation dual comparators offering lower offset voltage, higher supply voltage capability, lower current draw, improved ESD protection, and input ruggedness. These devices can replace existing LM293, LM393, and LM2903 versions. They operate from a single supply, feature independent circuits, and allow for wired-AND configurations.
