LM293 Description

Short technical summary and product information.

The Texas Instruments LM293 is an industrial-grade dual differential comparator. It is designed to operate over a wide temperature range of -25°C to 85°C and supports a supply voltage from 2V to 36V.

 

Key electrical characteristics include a typical quiescent current of 0.4mA per channel and a maximum offset voltage of 5mV at 25°C. The propagation delay time is 1.3µs. The output type is open-collector, open-drain, compatible with TTL, MOS, and CMOS logic levels.

 

This comparator is available in multiple package options, including VSSOP (DGK), PDIP (P), and SOIC (D). Its robust design makes it suitable for various industrial applications requiring reliable voltage comparison.

 

The LM293 is part of a family of dual comparators from Texas Instruments, with newer versions like the LM393B offering improved specifications such as lower offset voltage and faster response times.
