INTRODUCTION
This Technical Note describes the evaluation board for the AD7472 12-bit, high speed, low power, successive approximation A/D converter that operates from a single 2.7 V to 5.25 V supply. Full data on the AD7472 is available in the AD7472 data sheet available from Analog Devices and should be consulted in conjunction with this Technical Note when using the Evaluation Board.
On-board components include an AD780 which is a pin programmable +2.5 V or +3 V ultra high precision bandgap reference, two AD797 op-amps used to buffer the analog input, 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 on page 2.
