Introduction

　　The Texas Instruments LM57EVM evaluation module (EVM) helps designers evaluate the operation andperformance of the LM57. The LM57 is a precision, dual-output, temperature switch with an intearatedanalog temperature sensor., The programmable resistors allow user to set the Trip Temperature (TrRp)The LM57 can be programmed to any of 256 trip temperatures.

　　The EVM contains one LM57 Resistor-Programmable Temperature Switch and Analog TemperatureSensor. it comes pre-assembled with the LLP-8 LM57BlSD-10, and has a 10'C hysteresis of LM57. Theheader connector allows user to bring all package pins out for ease of characterization and testing.
