Product details

Dual comparator with wide supply tolerance

The LM2903M is a dual general-purpose comparator from Texas Instruments, designed for single-supply operation from 2V to 36V or dual supplies from ±1V to ±18V. The open-collector output stage sinks up to 16mA at 5V and interfaces directly with CMOS, TTL, DTL, ECL, or MOS logic families without external level shifters.

Quiescent current and input offset

Maximum quiescent current is 2.5mA — modest for a dual comparator but worth noting in battery-powered or current-limited rails. Input offset voltage is 7mV max at 30V supply, and input bias current is 0.25µA max at 5V, both typical for a general-purpose comparator of this generation.

Frequently asked questions

Can the LM393 replace the LM2903M?

The LM393 is a dual comparator with a similar pinout and open-collector output, but its supply range is typically 2V to 36V — check the specific variant's datasheet.
