High Accuracy Upgrade to Industry Standard LM75 / TMP75 I2C Temperature Sensor

High Accuracy Upgrade to Industry Standard LM75 / TMP75 I2C Temperature Sensor - TMP1075
 

Description

The TMP1075 is a lower power, higher accuracy 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 2x2 mm DFN reducing the PCB footprint by 79% compared to an SOIC package.

The TMP1075 provides 30% improvement in accuracy over standard xx75 temperature sensors 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 devices are ideal for temperature measurement in a variety of communication, computer, consumer, environmental, industrial, and instrumentation applications.

The TMP1075 devices are specified for operation over a temperature range of −55°C to +125°C.

The TMP1075 units are 100% tested on a production setup that is NIST traceable and verified with equipment that is calibrated to ISO/IEC 17025 accredited standards.
