AD5390/AD5391/AD5392 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 ...
Page 25
INTERFACES The AD5390/AD5391/AD5392 contain a serial interface that can be programmed to be either DSP-, SPI-, and MICROWIRE compatible C-compatible. The SPI/ I the interface mode. To minimize both the power consumption of the device and ...

AD5390/AD5391/AD5392 WRITE OPERATION There are three specific modes in which data can be written to the AD539x family of DACs. 4-BYTE MODE When writing to the AD539x DACs, begin with an address byte (R/W = 0), after ...
Page 29
MODE The 3-byte mode lets the user update more than one channel in a write sequence without having to write the device address byte each time. The device address byte is required only once and subsequent channel updates require ...
Page 30
AD5390/AD5391/AD5392 2-BYTE MODE The 2-byte mode lets the user update channels sequentially following initialization of this mode. The device address byte is required only once and the address pointer is configured for autoincrement or burst mode. The user must begin ...
