LM57 Temperature Switch/Analog Temperature Sensors

Texas Instruments LM57 Temperature Switch/Analog Temperature Sensors are 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 (0.5mm x 1mm), the LM57 can be programmed to any of 256 trip temperatures while consuming very little board space. The VTEMP output delivers an analog output voltage, which is proportional with a negative temperature coefficient (NTC) to the measured temperature. Texas Instruments LM57 Sensors are ideal for cellphones, wireless transceivers, digital cameras, PDAs, battery management, disk drive, and appliances.
