MCP6SX2DM-PCTLTH MCP6SX2 PGA Thermistor PICtail Demo Board

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 thermistor’s change in resistance over temperature.

A complete solution is achieved by interfacing this board to the PICkit™ 1 Flash Starter Kit (see DS40051) and the Signal Analysis PICtail™ Daughter Board (see DS51476). The solution provides:

PC software interface
PICmicro microcontroller
Firmware programmability
10-bit ADC (on the microcontroller)
Firmware (with re-locatable assembler code) for the microcontroller.
