Power-On Reset
The MAX5383/MAX5384/MAX5385 have a power-on
reset circuit to set the DAC’s output to 0 when VDD is
first applied or when VDD dips below 1.7V (typ). This
ensures that unwanted DAC output voltages will not
occur immediately following a system startup, such as
after a loss of power. The output glitch on startup is typ-
ically less than 50mV.
Shutdown Mode
The MAX5383/MAX5384/MAX5385 include three soft-
ware-controlled shutdown modes that reduce the supply
current to <1A. All internal circuitry is disabled, and a
known impedance is placed from OUT to GND to
ensure 0V while in shutdown. Table 2 details the three
shutdown modes of operation.
Digital Section
3-Wire Serial Interface
The MAX5383/MAX5384/MAX5385s’ 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 bits have been loaded into the serial
