Digital Interface
The MAX541/MAX542’s digital interface is a standard
3-wire connection compatible with SPI/QSPI/
MICROWIRE interfaces. The chip-select input (CS)
frames the serial data loading at the data-input pin
(DIN). Immediately following CS’s high-to-low transition,
the data is shifted synchronously and latched into the
input register on the rising edge of the serial clock input
(SCLK). After 16 data bits have been loaded into the
serial input register, it transfers its contents to the DAC
latch on CS’s low-to-high transition (Figure 3a). Note
that if CS is not kept low during the entire 16 SCLK
cycles, data will be corrupted. In this case, reload the
DAC latch with a new 16-bit word.
Alternatively, for the MAX542, LDAC allows the DAC
latch to update asynchronously by pulling LDAC low
after CS goes high (Figure 3b). Hold LDAC high during
the data-loading sequence.
External Reference
The MAX541/MAX542 operate with external voltage ref-
erences from 2V to 3V. The reference voltage deter-
mines the DAC’s full-scale output voltage. Kelvin
connections are provided with the MAX542 for optimum
performance.
Power-On Reset
The MAX541/MAX542 have a power-on reset circuit to
set the DAC’s output to 0V in unipolar mode when VDD
is first applied. This ensures that unwanted DAC output
voltages will not occur immediately following a system
power-up, such as after a loss of power. In bipolar
mode, the DAC output is set to -VREF.
