Description:
Although it is simple to measure temperature in a stand-alone system without the help of Microchip?s Programmable Gain Amplifiers (PGA), a variety of problems can be eliminated by implementing temperaturesensing capability in multiplexed applications with a PGA. One of the main advantages is that you can eliminate a second signal path to the microcontroller and still maintain the accuracy of your sensing system. In particular, the multiplexed PGAs you can use are the MCP6S22 (two-channel), MCP6S26 (six-channel), and MCP6S28 (eight-channel).
