The EVAL-AD7150EBZ is a fully featured evaluation board for the AD7150 which is ultra low power, 2 channel, capacitance converter for proximity sensing. The AD7150 delivers a complete signal processing solution for capacitive proximity sensors, featuring an ultra low power converter with fast response time. The AD7150 uses ADI's capacitance to digital converter (CDC) technology, which combines features important for interfacing to real sensors, such as high input sensitivity and high tolerance of both input parasitic ground capacitance and leakage current. The evaluation board can be operated in standalone mode (either battery powered or with external power supply) or connected to a PC via a standard USB interface. When operated with a PC, software is provided enabling the user to perform detailed analysis of the CDC's performance. This software includes the technical note describing the operation and set up of the evaluation board.
