Working Principle

The AD5064ARUZ-1 works on the principle of digital-to-analog conversion (DAC), wherein digitally encoded data is converted into an analog signal. In the case of the AD5064ARUZ-1, a 12-bit serial input signal is converted into an analog output signal.The process begins by converting the serial input data into a parallel word. This data is then converted into an analog signal using an R-2R ladder circuit. The signal is then amplified and buffered by a unity gain buffer, before being output as an analog signal.The AD5064ARUZ-1 also features a control logic block, which provides a convenient five-wire bus interface for direct control of the IC. This allows the user to directly control the DAC, via a serial interface, without the need for an external microcontroller.

Conclusion

The AD5064ARUZ-1 is an excellent choice for automatically converting digital input data into an analog signal. Its fast settling time, high-power efficiency, low error rate and ease of programming make it a great choice for applications such as industrial data acquisition, precision instrumentation, and embedded DAQ systems. Additionally, its on-board control logic block allows for direct control of the DAC from a standard PC software.
