The CDB3318 evaluation board is an excellent means for evaluating the CS3318 analog volume control. Evaluation requires an analog signal source and analyzer, power supplies, and a Windows PC compatible computer. Standard RCA phono jacks are provided to easily interface external analog signals with the evaluation board. Each of the CS3318’s inputs and outputs may be independently AC or DC-coupled to their respective I/O connectors. The Windows software provides a GUI to make configuration of the CDB3318 easy. The software communicates through the PC’s USB or Serial port to configure the control port registers so that all features of the CS3318 can be evaluated. As an alternative to the serial control provided via a PC, the evaluation board may be configured to accept external control signals for operation in a user application during system development.To facilitate multi-CS3318 system design efforts, headers are provided for connecting serial control signals between multiple CDB3318 evaluation boards.
