The Evaluation Board Controller (EVAL-CONTROL BOARD) is the main component in a complete self-contained evaluation and demonstration platform for Analog Devices precision analog-to-digital converters. The DSP-based controller board provides control and processing capability to configure and capture data from a range of ADC evaluation boards. Software for control, capture and processing of data in a PC environment is provided with each of the individual ADC evaluation boards.
The range of boards which are compatible with the Evaluation Board Controller are identified by a CB designator at the end of the part number in the evaluation board ordering number (e.g. EVAL-AD7266CB). Note the distinction between the above numbering and evaluation boards ending in a PCB designator. Combining the Evaluation Board Controller with any of the compatible ADC evaluation boards enables:
Setting up the evaluation platform for a particular ADC is a straight-forward task. The range of equipment required is the evaluation board for the ADC of interest, the Evaluation Board Controller and a 12V ac power supply block. The connection diagram for the evaluation platform is outlined below. For analysis of ac performance a quality signal source is required.
|Control Board||ADC Evaluation Board||12v AC Power Supply|
The 12V ac mains-powered power supply block comes in three different flavors and should be ordered when ordering the Evaluation Board Controller. For US and Japan, the model number is EVAL-110VAC-US; for Europe it is EVAL-220VAC-EU and for the UK, it is EVAL-220VAC-UK. Other regions in the world should order as per mains voltage requirements: either the 100 V-120 V or 200-240 V mains voltage standards.
Two versions of the Evaluation Board Controller are available, EVAL-CONTROL BRD2 and EVAL-CONTROL BRD3. Functionality on both boards is the same. The difference between the boards is the speed of the clock used on the on-board DSP and the memory size. Product web pages and datasheets will identify which version of the Evaluation Board Controller is compatible with any particular product.
