Evaluation Board

General Description

The CDB5571 is a versatile tool designed for evaluating the func-

tionality and performance of the CS5571 ADC (Analog-to-Digital

Converter). The SPI serial port on the CDB5571 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 CS5571 delta-sigma ADC produces fully settled conversions to

full specified accuracy at 100 kSps. This ability to produce fully set-

tled conversions for every sample makes it suitable for converting

multiplexed 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.

All evaluation board functionality for evaluating the CS5571 ADC is

accessed through the connector interface and board-level options.

Schematics in PADS™ PowerLogic™ format are available for
