GENERAL DESCRIPTION
The AD5424/AD5433/AD54451 are CMOS 8-, 10-, and 12-bit
current output digital-to-analog converters (DACs), respectively.
These devices operate from a 2.5 V to 5.5 V power supply,
making them suitable for battery-powered applications and
many other applications. These DACs utilize data readback,
allowing the user to read the contents of the DAC register via
the DB pins. On power-up, the internal register and latches are
filled with 0s and the DAC outputs are at zero scale.
As a result of manufacturing with a CMOS submicron process,
they offer excellent 4-quadrant multiplication characteristics,
with large signal multiplying bandwidths of up to 10 MHz.
The applied external reference input voltage (VREF) determines the
full-scale output current. An integrated feedback resistor (RFB)
provides temperature tracking and full-scale voltage output
when combined with an external I-to-V precision amplifier.
While these devices are upgrades of the AD5424/AD5433/
AD5445 in multiplying bandwidth performance, they have a
latched interface and cannot be used in transparent mode.
The AD5424 is available in small, 20-lead LFCSP and 16-lead
TSSOP packages, while the AD5433/AD5445 DACs are available
in small, 20-lead LFCSP and TSSOP packages.
The EVAL-AD5445SDZ evaluation board is available for
evaluating DAC performance. For more information, see the
UG-333 evaluation board user guide.
