Interfacing a MCP9700 Analog Output Temperature Sensor to a PICmicro Microcontroller
Analog output silicon temperature sensors offer an easy-to-use alternative to traditional temperature sensors, such as thermistors. The MCP9700 offers many system-level advantages, including the integration of the temperature sensor and signal-conditioning circuitry on a single chip. Analog output sensors are especially suited for embedded systems due to their linear output. This application note will discuss system integration, firmware implementation and PCB layout techniques for using the MCP9700 in an embedded system. The firmware required to interface the MCP9700 to a microcontroller is demonstrated using the PICkit 1 Flash Starter Kit.
