Consideration of Analog Front-End (AFE) Module

In InstaSPIN applications, motor line current and phase voltage are required by the algorithm. Before these analog signals are sampled by the processor, all signals are processed by an analog circuit. The external analog circuits add component cost and increase board size. The 2805x series of processors addresses this issue by adding internal analog conditioning components for the motor feedback signals, called the analog front end (AFE).
