MCP6SX2DM-PCTLTH

The MCP6SX2DM-PCTLTH is a MCP6SX2 PGA thermistor PICtail demo board containing the MCP6S22 and MCP6S92 Programmable Gain Amplifiers (PGA). The PGA are based on a simple analog building blocks and the voltage is processed in the analog domain by MCP6SX2 (MCP6S22 or MCP6S92) PGA before conversion to the digital domain. The device 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 user to experiment with different designs on the bench. DIP switches on the board select certain resistors to add together, thereby emulating the series resistor in the voltage divider and the thermistor's change in resistance over temperature.

• On board thermistor can select a high accuracy NTC thermistor and emulator for quick bench work
• Voltage divider linearizes thermistor response
• Series resistor has an emulator for quick prototyping of different designs
• PGA buffers the NTC Thermistor
• Increases linearity and temperature resolution
• PGA provides an additional input
• SMD test points
