TIDA-00110, Analog Front End (AFE) for Sensing Temperature in Smart Grid Applications Using RTD Reference Design

TIDA-00110, Analog Front End (AFE) for Sensing Temperature in Smart Grid Applications Using RTD Reference Design. This reference design enables up to 4 Resistor Temperature Detectors (RTD) to be connected through one ADC in manner such that the solution is both compact and modular. Communication from the ADC to the processor is though an SPI interface. If 8 RTDs are required for an application, simply connect up one more of these modules. This solution is flexible to where it can handle 2 wire, 3 wire or 4 wire type RTDs
