http://www.microchip.com/analog The MCP6SX2 PGA Thermistor PICtail Demo Board features the MCP6S22 and MCP6S92 Programmable Gain Amplifiers (PGA). These devices help:
 Overcome the non-linear response of the on-board NTC thermistor
 Provide multiplexing between two inputs; the other input can be any desired source. This opens the possibilities of temperature correcting another sensor, and of increasing the number of PIC® microcontroller I/O pins available for other purposes.

Two on-board variable resistors allow users to experiment with different designs on the bench. DIP switches on the board select certain resistors (in a binary weighted sequence) to add together, thereby emulating the series resistor in the voltage divider and the thermistors change in resistance over temperature.
