GENERAL DESCRIPTION
The AD5425 is a CMOS 8-bit current output digital-to-analog
converter that operates from a 2.5 V to 5.5 V power supply,
making it suited to battery-powered applications and many
other applications.
This DAC utilizes a double buffered 3-wire serial interface that
is compatible with SPI
, QSPI, MICROWIRE, and most
DSP interface standards. In addition, an
LDAC
pin is provided,
which allows simultaneous update in a multi-DAC configuration.
On power-up, the internal shift register and latches are filled
with 0s and the DAC outputs are at 0 V.
As a result of processing on a CMOS submicron process, this
DAC offers excellent 4-quadrant multiplication characteristics,
with large signal multiplying bandwidths of 10 MHz.
The applied external reference input voltage (V
REF
) determines
the full-scale output current. An integrated feedback resistor (R
FB
)
provides temperature tracking and full-scale voltage output
when combined with an external I-to-V precision amplifier.
The AD5425 DAC is available in a small 10-lead MSOP package.
