GENERAL DESCRIPTION
The EVAL-AD4052-ARDZ enables quick and easy evaluation of
the performance and features of the AD4052. The AD4052 is a
compact, low power, 16-bit Easy Drive successive approximation
register (SAR) analog-to-digital converter (ADC).
The primary controller board for the EVAL-AD4052-ARDZ is the
SDP-K1. The EVAL-AD4052-ARDZ conforms to the Arduino
Shield mechanical and electrical standards to interface with the
SDP-K1, in addition to various software development kits from other
manufacturers.
The AD4052 evaluation solution includes the AD4052 industrial
input and output (IIO) firmware application drivers for device con-
figuration and ADC data capture and the AD4052 ACE plugin
graphical user interface (GUI) for performance evaluation.

Refer to the... - Page 4 If no signal generator is available, a jumper cable between the VREF and VCM test points can be used to bias the AD4052 analog inputs to VREF. This is preferred over connecting the amplifier inputs to GND, because the amplifier VEE rails are connected to GND by default.
