Silicon temperature sensor

25 January 2012 Test & Measurement

New from Microchip is the MCP9808 silicon temperature sensor, which serves a broad range of applications by guaranteeing high accuracy of 0,5°C from -20°C to +100°C, combined with high temperature resolution of 12 bits (0,0625°C/LSB). It comes in small MSOP and 2 x 3 mm DFN 8-pin packages and additional features include shutdown, an under/over-temperature monitor and a critical temperature alert.

Target applications include thermostats operating at -20°C to +45°C; personal computers operating at +85°C and industrial or automotive applications which have an operating temperature of up to 125°C. In addition, many applications can benefit from reduced energy consumption via accurate temperature monitoring and control that enables more efficient operation. With its shutdown and temperature monitoring/alert features, the MCP9808 can help to adjust the real-time power utilisation of applications ranging from residential HVAC systems to industrial equipment.
