GENERAL DESCRIPTION
The EVAL-AD4050-ARDZ and EVAL-AD4052-ARDZ evaluation
boards enable quick and easy evaluation of the performance and
features of the AD4050 or the AD4052, respectively. The AD4050
and AD4052 are compact, low power, 12-bit or 16-bit (respectively)
Easy Drive successive approximation register (SAR) analog-to-digi-
tal converters (ADCs).
The primary controller board for the EVAL-AD4050-ARDZ/EVAL-
AD4052-ARDZ is the SDP-K1. The EVAL-AD4050-ARDZ/EVAL-
AD4052-ARDZ conform to the Arduino
and electrical standards to interface with the SDP-K1, in addition to
various software development kits from other manufacturers.
The AD4050/AD4052 evaluation solutions include the AD4050/
AD4052 industrial input and output (IIO) firmware application driv-
ers for device configuration and ADC data capture and the AD4050/
AD4052 ACE plugin graphical user interface (GUI) for performance
evaluation.
