ADuM7702 16-Bit, Isolated Sigma-Delta Modulators

ADI's ADuM7702 enables system miniaturization and the reduction of torque ripple specification that improves the performance and robustness of a motor control system. Proven iCoupler® isolation technology offers safety and system reliability and allows for higher bus voltages in the inverter design, further improving drive efficiency. Excellent CMTI rating enables faster switching times and reduces dead time often associated with the newest switching technologies such as GaN and SiC.

The EV-ADuM7702-8FMCZ is a fully featured evaluation board that allows the user to evaluate all the features of the ADuM7702 isolated analog-to-digital converter (ADC). The EVAL-SDP-CH1Z (SDP-H1) high-speed system demonstration platform (SDP) controller board controls the EV-ADuM7702-8FMCZ via the J9 connector and through the USB port of a PC using the analysis, control, evaluation (ACE) software. The ACE software is available to download on the ACE software page.
