Description:

Resistor-programmable temperature switch and analog temperature sensor.

LM57, Resistor-Programmable Temperature Switch And Analog Temperature Sensor

The LM57 is a precision, dual-output, temperature switch with integrated analog temperature sensor.

The trip temperature (TTRIP) is programmable by using two external 1% resistors.

Using extremely small packaged resistors (0.5 mm x 1 mm), the LM57 can be programmed to any of 256 trip temperatures wh

LM57 Features

* Trip temperature set by external resistors

* External resistor tolerance contributes zero error

* Push-pull and open-drain temperature switch outputs

* Wide operating temperature and trip-temperature range of

* 50°C to 150°C

* Very linear analog VTEMP temperature sensor
