... The AD7390 will only respond to the last 12 bits clocked into the SDI input, however, so the serial-data (4) interface is not affected. Ten data bits are required to load a value into the AD7391. If more than 10 bits are transmitted before load LD returns high, the extra bits are ignored. . The micropower REF195 is guaranteed ...
