EVAL-CN0565-ARDZ

EVAL-CN0565-ARDZ is a CN0565 circuit evaluation board. The EVAL-CN0565-ARDZ is an electrical impedance tomography (EIT) measurement system for characterizing and computing interior impedance of surfaces. The platform allows a conductivity map to be reconstructed using several repeating measurements from electrodes placed at different locations. It supports impedance measurement setups with up to 24 electrodes. The design uses a pair 8×12 analogue crosspoint switches, which enables the excitation signal to be applied to one pair of electrodes at a time. The implementation of crosspoint switches allows the circuit to maximize the impedance measurements, which consequently improves the resolution of the constructed images. The design also features a complete power and signal isolation to the host controller, which can be used as reference for bioimpedance applications.
