LM293DR2 Description

Short technical summary and product information.

The LM293DR2 from On Semiconductor is a dual, independent precision voltage comparator. It is designed for single or split supply operation and allows for a common-mode range down to ground level with single supply operation. This comparator features a wide single-supply range from 2.0 Vdc to 36 Vdc and a split-supply range from ±1.0 Vdc to ±18 Vdc.

Key electrical characteristics include very low current drain (0.4 mA) independent of supply voltage, low input bias current of 25 nA, and low input offset current of 5.0 nA. The input offset voltage is a maximum of 5.0 mV. The differential input voltage range is equal to the power supply voltage, and the output voltage is compatible with DTL, ECL, TTL, MOS, and CMOS logic levels.

This device is available in an 8-SOIC package, suitable for surface mounting. It operates within various temperature ranges depending on the specific variant, with options including 0°C to 70°C and -40°C to 125°C. The LM293DR2 is Pb-free and Halogen-free.

Applications for the LM293DR2 include consumer, automotive, and industrial electronics where precision voltage comparison is required.
