The LM95172EWG is an integrated digital-output temperature sensor with a Serial Peripheral Interface (SPI) and MICROWIRE™-compatible interface in a 10-pin Cerpack high temperature ceramic package. It features a very linear Sigma-Delta Analog-to-Digital Converter (ADC), high accuracy, fast conversion rates, and extremely low output noise. With an operating temperature as low as -40°C and optimized accuracy from 120°C to 200°C, it is ideal for high-temperature applications.
The over-temperature alarm output (OVERTEMP) asserts when the die temperature exceeds a programmed THIGH limit. The user-programmed TLOW limit creates a temperature-stabilizing hysteresis when the ambient temperature is near the trip point.
The LM95172EWG can be programmed to operate from 13 bits (0.0625°C per LSB) to 16 bits (0.0078125°C per LSB) resolution. The LM95172EWG powers up in 35 ms, the fastest conversion time, with temperature output set at 13-bit resolution. The resolution may then be changed to 14-, 15- or 16-bits. When in the 13-, 14- or 15-bit resolution mode, the least significant bit in the 16-bit temperature register toggles after the completion of each conversion. This bit may be monitored to verify that the conversion is complete.
The high noise immunity of the Serial I/O (SI/O) output makes the LM95172EWG ideal for use in challenging electromagnetic environments.
