... Evaluation Board For AD7682/89/99/7949 www.analog.com evaluation board. The evaluation board can be operated as a stand alone or can be used in conjunction with the Analog Devices EVAL-CED1Z (CED) USB based data capture board. Since the ADC’s being evaluated are serial interface only, the EVAL-AD76MUXCBZ contains the necessary logic to perform serial to parallel conversion for this interface using the on board FPGA ...

... AC test, apply a sinusoidal signal to the evaluation board at the SMB inputs J1 for CH0 and J2 for CH1. Low distortion, better than 100dB, is required to allow true evaluation of the part. One possibility is to filter the input signal from the AC source. There is no suggested bandpass filter but Rev. PrD | Page ...
