... This board can be used as a standalone evaluation board or in conjunction with the EVAL-CONTROL BRD2 for evaluation/demonstration purposes. 2 This board allows control and communicate with all Analog Devices evaluation boards ending in the CB designators. CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection ...

SERIAL INTERFACE The AD7676 is configured to use the serial interface when the SER/PAR is held HIGH. The AD7676 outputs 16 bits of data MSB first, on the SDOUT pin. This data is synchronized with the 16 clock pulses provided ...
Page 16
AD7676 In Read-after-Conversion Mode, unlike in other modes, it should be noted that the signal BUSY returns LOW after the 16 data bits are pulsed out and not at the end of the conversion phase, which results in a longer ...
