TMP1075 IC Chip

TMP1075 (Temperature Sensor With I²C and SMBus Interface in Industry Standard LM75 Form Factor and Pinout)

Introduction

The TMP1075 is the most accurate and lowest power replacement to the industry standard LM75 and TMP75 digital temperature sensors. Available in SOIC-8 and VSSOP-8 packages, the TMP1075 offers pin-to-pin and software compatibility to quickly upgrade any existing xx75 design. An additional new package with the TMP1075 is 2×2 mm DFN reducing the PCB footprint by 79% compared to an SOIC package.

The TMP1075 has a ±1°C accuracy over a wide temperature range and offers an on-chip 12-bit analog-to-digital converter (ADC) providing a temperature resolution of 0.0625°C.

Compatible with two-wire SMBus and I²C interfaces,the TMP1075 supports up to 32 devices address and provides SMBus Reset and Alert function.

The TMP1075 is designed for accurate and cost-effective temperature measurement in virtually any telecommunication,enterprise, industrial and personal electronics equipment.
