GENERAL DESCRIPTION
The AD54251 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 suitable for 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. An LDAC pin is also provided, which
allows simultaneous updates in a multi-DAC configuration. On
power-up, the internal shift register and latches are filled with
0s and the DAC outputs are 0 V.
As a result of manufacturing on a CMOS submicron process,
this DAC offers excellent 4-quadrant multiplication charac-
teristics 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 I-to-V precision amplifier.
The AD5425 is available in a small, 10-lead MSOP package.
