INTRODUCTION
This Technical Note describes the operation and functionality
of the Evaluation Board for the AD5370, AD5372 and AD5373.
As these 3 parts are pin compatible the same evaluation board is
used for all. AD537x will be used throughout this technical note
to refer to the actual multi-channel DAC used on the board.
This note should be used in conjunction with the data sheet of
the appropriate DAC. The evaluation board allows the
functionality and performance of the AD537x to be evaluated
easily. The evaluation board can be used as a stand alone board
with control coming from an external DSP or micro-controller
or it can be connected to a PC. Software is provided which can
be used to program the registers of the AD537x. Control of the
AD537x is achieved via a USB interface
