... Evaluation Board Overview The CDB5530U evaluation board is partitioned into two main sections — analog and digital. The analog section consists of the CS5530 and a precision voltage reference. The digital section consists of the mi- crocontroller, the reset circuitry, and the USB interface. The board also has power supply connections which accommodate all of the various supply options of the CS5530. The evaluation board’ ...

... Note that the VA- supply should be connected to ground when powering the CDB5530U from a single +5 V analog supply. VD+ supplies the digital section of the ADC and level shifters. Header J15 allows the VD+ supply to be sourced from the VD+ binding post (J5), the +5 V binding post (J3), or the regulated +3.3 V supply derived from the microcontroller. The +5 V bind- ing post supplies the microcontroller’ ...

... After a reset, the registers will all return to their default values as discussed in the CS5530 data sheet. Read Data: This button will instruct the ADC to begin performing repeated single (fully-settled) conver- sions on the setup channel specified by the Setup Register box. The results of the most recent conversion 10 Figure 5. CDB5530U Setup Window CDB5530U DS742DB1 ...
