Serial Interface
The 3-wire serial interface (SPI, QSPI, and MICROWIRE
compatible) used in the MAX5234/MAX5235 allows for
complete control of DAC operations (Figures 4 and 5).
Figures 1 and 2 show the timing for the serial interface.
The serial word consists of 3 control bits followed by 12
data bits (MSB first) and 1 sub-bit as described in
Tables 1, 2, and 3. When the 3 control bits are all zero
or all 1, D11
–
D8 are used as additional control bits,
allowing for greater DAC functionality.
The digital inputs allow any of the following: loading the
input register(s) without updating the DAC register(s),
updating the DAC register(s) from the input register(s),
or updating the input and DAC register(s) simultane-
ously. The control bits and D11
–
D8 allow the DACs to
operate independently.
Send the 16-bit data as one 16-bit word (QSPI) or two
8-bit packets (SPI and MICROWIRE), with
CS
low dur-
ing this period. The control bits and D11
–
D8 determine
which registers update and the state of the registers
when exiting shutdown. The 3-bit control and D11
–
D8
determine the following:
Registers to be updated
Selection of the power-down modes
The general timing diagram of Figure 1 illustrates data
acquisition. Driving
CS
low enables the device to
receive data. Otherwise, the interface control circuitry is
disabled. With
CS
low, data at DIN is clocked into the
