The LM95172Q is a digital temperature sensor with industryleading accuracy at temperatures up to 175C. It features a linear Sigma-Delta Analog-to-Digital Converter (ADC) with fast conversion rates and low output noise. Communication with the LM95172Q is achieved over an easy-to-use Serial Peripheral Interface (SPI) with high noise immunity. The LM95172Q's resolution is user programmable from 0.0625C to 0.0078125C. When operating in 13-, 14- or 15bit resolution, the LM95172Q indicates a new conversion has been completed. The LM95172Q also features an over-temperature alarm output (OVERTEMP) that asserts when the die temperature exceeds a programmed high limit. The LM95172Q is specified for operation over the wide temperature range of -40C to 175C. It is available in die form which makes the LM95172Q ideal multi-chip modules or custom packaging to a wide variety of high-temperature applications.
