LM2903DT Description

Short technical summary and product information.

The LM2903DT is a reliable, low-power dual voltage comparator from STMicroelectronics, widely used in automotive and industrial applications. It supports a wide supply voltage range from 2V to 36V, offering flexibility for various designs.

 

Key specifications include 2 channels and a response time of 1.3 µs. The comparator features an open-collector output, which is common in such devices for interfacing with different voltage levels.

 

This component is best suited for general-purpose voltage comparison in automotive systems and industrial control. It should be avoided for high-speed applications requiring sub-microsecond response times. The input common-mode voltage range should be checked before use in specific designs.
