GENERAL DESCRIPTION
The AD5426/AD5432/AD54431 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 use a 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 manufacturing on a CMOS submicron process,
the parts offer excellent 4-quadrant multiplication characteristics
with large signal multiplying bandwidths of 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 current to voltage precision amplifier.
The AD5426/AD5432/AD5443 DACs are available in small,
10-lead MSOP packages.
The EV-AD5443/46/53SDZ evaluation board is available for
evaluating DAC performance. For more information, see the
UG-327 evaluation board user guide.
