GENERAL DESCRIPTION
The AD5426/AD5432/AD5443 are CMOS 8-, 10-, and 12-bit
current output digital-to-analog converters, respectively.
These devices operate from a 3.0 V to 5.5 V power supply,
making them suited to battery-powered applications and many
other applications.
These DACs utilize double buffered 3-wire serial interface that
is compatible with SPI
, QSPI, MICROWIRE, and most
DSP interface standards. In addition, a serial data out pin (SDO)
allows for daisy-chaining when multiple packages are used. Data
readback allows the user to read the contents of the DAC register
via the SDO pin. On power-up, the internal shift register and
latches are filled with 0s and the DAC outputs are at zero scale.
As a result of manufacture on a CMOS submicron process, they
offer 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 current to voltage precision amplifier.
The AD5426/AD5432/AD5443 DACs are available in small
10-lead MSOP packages.
