AN65977 - PSoC® 3, PSoC 4, and PSoC 5LP - Temperature Measurement with a TMP05/TMP06 Digital Sensor

AN65977 describes the TMP05 Digital Temperature Sensor Interface Component, which is a building block for thermal management applications. It enables designers using PSoC to quickly and easily interface with multiple Analog Devices TMP05 or TMP06 digital temperature sensors through a simple, serial 2-wire digital interface.

Introduction

Digital temperature sensors are widely used in systems where multiple temperature measurements are required in specific locations on a large board (such as a line card in a switch or router) or in a remote location. The use of digital temperature sensors frees the designer from worrying about digital noise coupling on to sensitive analog signals on the PCB layout because the digital temperature sensor does the analog to digital conversion within its own package, at the location where the temperature measurement is needed.

The TMP05 Digital Temperature Sensor Interface Component is a building block for thermal management applications. It enables designers using PSoC 3 to quickly and easily interface with Analog Devices’ TMP05 or TMP06 digital temperature sensors through a simple, serial 2-wire digital interface. The sensors can be daisy-chained together, minimizing I/O requirements on the controller. For more details on the specific functions of the TMP05 Digital Temperature Sensor Interface Component, refer to the component datasheet.
