INTRODUCTION
The EVAL-AD7716EB demonstrates the AD7716, 4-channel,
22-bit A/D Converter. This high-resolution ADC is ideally
suited for biomedical data acquisition systems such as ECG and
EEG as will as general data acquisition applications. Full data
on the AD7716 is available in the AD7716 data sheet availale
from Analog Devices and should be consulted in conjuction
with this document when using the evaluation board.
Included on the evaluation board with the AD7716 are 4 input
buffers, a voltage reference, a crystal oscillator, output interface
circuitry and a 25-Way D-Type connector. The board comes
complete with a cable for connecting directly to the printer port
of a PC.
Software is provided to allow simple demonstration and
evaluation of the AD7716.
