MCP9808 Silicon Temp Sensor



Microchip's sensor provides +/- 0.5°C accuracy and 12-bit resolution from -20 to +100°C offered in packages as small as 2x3 mm DFN


Microchip MCP9808 Silicon Temp Sensor Microchip's MCP9808 serves a broad range of applications by guaranteeing high accuracy of 0.5 degrees from -20 to +100 degrees Celsius, along with high temperature resolution of 12 bits (0.0625 degrees Celsius/LSB). The MCP9808 comes in small MSOP and 2x3 mm DFN 8-pin packages, for space-constrained applications. Additional features include shutdown, an under/over-temperature monitor and a critical-temperature alert. Many applications require high accuracy over a variety of temperatures, such as thermostats (-20 to +45°C), personal computers (+85°C) and industrial/automotive (+125°C). With its extremely high accuracy levels over a wide temperature range, the MCP9808 is well suited for all of these applications and more.
