Microchip | MCP9700AT-E/LT

The MCP9700A family of Linear Active Thermistor™ ICs are sensors whose output voltage is directly proportional to measured temperature. The MCP9700A can accurately measure temperature from -40°C to +125°C.

The output of the MCP9700A is calibrated to a slope of 10mV/°C and has a DC offset of 500 mV. The offset allows reading negative temperatures without the need for a negative supply. The MCP9700A is packaged in space saving 5-pin SC-70, and 3-ld TO-92 packages.
