General Description
The CDB5566 is a versatile tool designed for evaluating the func-
tionality and performance of the CS5566 ADC (Analog-to-Digital
Converter). The SPI serial port on the CDB5566 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 CS5566 delta-sigma ADC produces fully settled conversions to
full specified accuracy at 5 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 CDB5566
includes two differential analog inputs multiplexed into the CS5566.
The multiplexer can be switched at the CS5566 ADC sample speed
and the ADC will produce fully settled conversion data for each input
channel.
All evaluation board functionality for evaluating the CS5566 ADC is
accessed through the connector interface and board-level options.
