The CDB5464U is an inexpensive tool designed to evaluate the functionality and performance of the CS5464 analog-to-digital converter (ADC). The evaluation board includes an LT1019 voltage reference, a C8051F320 microcontroller with a USB interface, and firmware. The microcontroller controls the serial communication between the evaluation board and the PC via the firmware, enabling quick and easy access to all of theCS5464's registers and functions.
