GENERAL DESCRIPTION
The AD5426/AD5432/AD5443
current output digital-to-analog converters (DACs), respectively.
These devices operate from a 3 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
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, V
output current. An integrated feedback resistor, R
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.
