Description

This is Dual differential comparator.

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.

These devices consist of two independent voltage comparators that are designed to operate from a single power supply over a wide range of voltages. Operation from dual supplies also is possible as long as the difference between the two supplies is 2 V to 36 V, and V CC is at least 1.5 V more positive than the input common-mode voltage. Current drain is independent of the supply voltage. The outputs can be connected to other open-collector outputs to achieve wired-AND relationships.

Features

1. Common-mode input voltage range includes ground

2. Differential input voltage range equal to maximum-rated supply voltage : ±38 V

3. Low output saturation voltage

4. Output compatible with TTL, MOS, and CMOS

Applications:

• Vacuum robot
• Single phase UPS
• Server PSU
• Cordless power tool
• Wireless infrastructure
• Applicances
• Building automation
• Factory automation & control
• Motor drives
• Infotainment & cluste
