描述 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.特性LM95172EWG is AEC-Q100 Grade 0 Qualified and is Manufactured on an Automotive Grade Flow. 13-Bit (0.0625°C LSB) to 16-Bit (0.0078125°C LSB) Temperature Resolution Wide −40°C to +200°C Temperature Range 35 ms Best Conversion Time Tracks Fast Temp Changes OVERTEMP Digital Output Switches when TDIE > THIGH Shutdown Mode Saves Power yet Wakes up for One-Shot Temperature Update SPI and MICROWIRE Bus Interface 10-Pin Cerpack High-Temperature Ceramic Package Key Specifications Analog and Digital Supply Voltage 3.0V to 5.5V Total Supply Current     Operating 400 µA (typ)Shutdown −40°C to +140°C 4 µA (max)Shutdown −40°C to +175°C 12 µA (max)Shutdown −40°C to +200°C 28 µA (max) Temperature Accuracy+175°C to +200°C ±3.0°C (max)+130°C to +160°C ±1.0°C (max)+120°C to +130°C ±2.0°C (max)+160°C to +175°C ±2.0°C (max)−40°C to +120°C ±3.5°C (max) Temperature Resolution13-bit mode 0.0625°C/LSB16-bit mode 0.0078125°C/LSB Conversion Time13-bit mode 43 ms (max)16-bit mode 350 ms (max) All trademarks are the property of their respective owners.
