Description
The CDB3318 evaluation board is an excellent means
for evaluating the CS3318 analog volume control. Eval-
uation requires an analog signal source and analyzer,
power supplies, and a Windows PC compatible
computer.
Standard RCA phono jacks are provided to easily inter-
face external analog signals with the evaluation board.
Each of the CS3318’s inputs and outputs may be inde-
pendently AC or DC-coupled to their respective I/O
connectors.
The Windows software provides a GUI to make config-
uration 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 exter-
nal control signals for operation in a user application
during system development.
To facilitate multi-CS3318 system design efforts, head-
ers are provided for connecting serial control signals
between multiple CDB3318 evaluation boards.
