CDB5571
1. INTRODUCTION
The CDB5571 evaluation board is a platform for evaluating the CS5571 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
CDB5571 and other Cirrus Logic evaluation boards.
The CDB5571 evaluation board is designed to simplify the hardware setup required to evaluate the
CS5571. Interfacing the CDB5571 evaluation board to a user-supplied data capture system can be as
simple as connecting the SPI port and using the CDB5571 default hardware configuration. In this config-
uration, simply press the Reset switch on the CDB5571 and it will automatically begin transmitting data to
the data capture system.
All evaluation board functionality for evaluating the CS5571 ADC is accessed through the connector in-
terface and board-level options.
The CS5571 delta-sigma ADC produces fully settled conversions to full specified accuracy at 100 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 CDB5571 includes two single-ended analog inputs
multiplexed into the CS5571. The multiplexer can be switched at the CS5571 ADC sample speed and
the ADC will produce fully settled conversion data for each input channel.
