LM393M Description

Short technical summary and product information.

The LM393M from Texas Instruments is a dual independent precision voltage comparator. It is designed for single or split supply operation and supports a common-mode range to ground level.

 

Key electrical specifications include a wide single-supply range of 2.0 Vdc to 36 Vdc and a split-supply range of ±1.0 Vdc to ±18 Vdc. The device exhibits very low current drain, independent of supply voltage, at 0.4 mA. It features a low input bias current of 25 nA and a low input offset current of 5.0 nA. The maximum input offset voltage is 5 mV at 30V, and the maximum propagation delay is 700 ns.

 

This comparator is compatible with DTL, ECL, TTL, MOS, and CMOS logic levels. It operates within an ambient temperature range of 0°C to 70°C. The device is housed in an 8-SOIC package and is surface-mounted.

 

Environmental compliance includes RoHS3 status and is Pb-Free, Halogen Free/BFR Free.
