TI TMP175AIDR

The TMP75 and TMP175 are digital temperature sensors and ideal replacements for NTC and PTC thermistors. These devices require no calibration or external component signal conditioning to provide typical accuracy of ±1°C. The on-chip temperature sensor is highly linearized, eliminating the need for complex calculations or lookup tables to determine temperature. The on-chip 12-bit ADC offers resolution as low as 0.0625°C. The devices are available in the industry-standard LM75 SOIC-8 and MSOP-8 package footprints. The TMP175 and TMP75 are compatible with SMBus, two-wire, and I2C interfaces. The TMP175 supports up to 27 devices on a single bus. The TMP75 supports up to eight devices on a single bus. Both the TMP175 and TMP75 feature SMBus Alert functionality. The TMP175 and TMP75 are suitable for extended temperature measurement in a wide range of applications including communications, computing, consumer electronics, environmental monitoring, industrial, and instrumentation. The TMP175 and TMP75 are rated for operation over a temperature range of −40°C to +125°C. TMP75 production units are fully tested with NIST-traceable sensor testing and verified using NIST-traceable equipment with ISO/IEC 17025-accredited calibration.
