General Description

The CDB5560 is a versatile tool designed for evaluating the func-
tionality and performance of the CS5560 ADC (Analog-to-Digital
Converter). The SPI serial port on the CDB5560 evaluation board
is configured in Master mode and will start transmitting data after
power-up upon reset. This evaluation board is designed to connect
to your data capture system or will interface to the CapturePlus II
data acquisition system available from Cirrus Logic.
The CS5560 delta-sigma ADC produces fully settled conversions to
full specified accuracy at 50 kSps. This 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.
All evaluation board functionality for evaluating the CS5560 ADC is
accessed through the connector interface and board-level options.
