GENERAL DESCRIPTION

This data sheet describes the evaluation board for the AD7470/AD7472. The AD7470/AD7472 are, respectively, 10-/12-bit, high speed, low power, successive approximation ADCs that operate from a single 2.7 V to 5.25 V supply. Full data on the AD7470/AD7472 is available in the AD7470/AD7472 data sheet available from Analog Devices, Inc. and should be consulted in conjunction with this data sheet when using the evaluation board.

On-board components include an AD780 (a pin programmable +2.5 V or +3 V ultra high precision band gap reference), an AD797 and an AD711 (op amps used to buffer the bipolar and unipolar analog input respectively), and an OP07 (op amp used to buffer the DC bias voltage applied to the optional analog input bias-up circuit). There are various link options, which are explained in detail in the Link and Switch Options section.

Interface to this board is via a 96-way connector. This 96-way connector is compatible with the EVAL-CONTROL BRD2 (also available from Analog Devices). External sockets are provided for the CNVST input, CLKIN input, and the VIN inputs.
