... DATA DECODING AD5390/AD5392 The AD5390/AD5392 contain an internal 14-bit data bus. The input data is decoded depending on the data loaded to the REG1 and REG0 bits of the input serial register. This is shown in Table 10. Data from the serial input register is loaded into the addressed DAC input register, offset (c) register, or gain (m) register. The format data, and the offset (c) and gain (m) register contents are shown in Table 11 to Table 13 ...
