TMP175AIDRG4

数字温度传感器，具有双线接口 Digital Temperature Sensor with Two-Wire Interface

Description

The TMP75 and TMP175 devices are digital temperature sensors ideal for negative temperature coefficient NTC and positive temperature coefficient PTC thermistor replacement. The devices offer a typical accuracy of ±1°C without requiring calibration or external component signal conditioning. Device temperature sensors are highly linear and do not require complex calculations or look-up tables to derive the temperature. The on-chip 12-bit analog-to digital converter ADC offers resolutions down to 0.0625°C. The devices are available in the industry standard LM75 SOIC-8 and MSOP-8 footprint.
