General Description

The LM57 device is a precision, dual-output, temperature switch with analog temperature sensor output for wide temperature industrial applications.

The trip temperature (TTRIP) is selected from 256 possible values in the range of –40°C to 150°C.

The VTEMP is a class AB analog voltage output that is proportional to temperature with a programmable negative temperature coefficient (NTC).
