CDB5560
1. INTRODUCTION
The CDB5560 evaluation board is a platform for evaluating the CS5560 ADC performance. The evalua-
tion board is designed to connect to the SPI serial port of a processor or data capture system or will inter-
face directly to the CapturePlus II data acquisition system available from Cirrus Logic. The CapturePlus II
data acquisition system is a powerful integrated hardware/software tool designed to fully exercise the
CDB5560 and other Cirrus Logic evaluation boards.
The CDB5560 evaluation board is designed to simplify the hardware setup required to evaluate the
CS5560. Interfacing the CDB5560 evaluation board to a user-supplied data capture system can be as
simple as connecting the SPI port and using the CDB5560 default hardware configuration. In this config-
uration, simply press the Reset switch on the CDB5560 and it will automatically begin transmitting data to
the data capture system.
All evaluation board functionality for evaluating the CS5560 ADC is accessed through the connector in-
terface and board-level options.
The CS5560 delta-sigma ADC produces fully settled conversions to full specified accuracy at 50 kSps.
The ability to produce fully settled conversions for every sample makes it suitable for converting multi-
plexed input signals. To help evaluate this feature, the CDB5560 includes two differential analog inputs
multiplexed into the CS5560. The multiplexer can be switched at the CS5560 ADC sample speed and
the ADC will produce fully settled conversion data for each input channel.
