The AD5425 is a CMOS, 8-bit current output digital-to-analog converter (DAC), which operates from a 2.5 V to 5.5 V power supply, making it suited to 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 processing on a CMOS sub micron process, this DAC offers 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 I to V precision amplifier.
The AD5425 is available in a small, 10-lead MSOP package.

Precision DAC Error Budget Tool
The Precision DAC Error Budget Tool is a web application that calculates the DC Accuracy of precision DAC signal chains. It shows how the static errors accumulate throughout your signal chain to quickly evaluate the design tradeoffs. Calculations include the DC errors introduced by Voltage References, Operation Amplifiers and Precision DACs.
