High Bandwidth, CMOS 8-Bit Serial Interface Multiplying D/A Converter
The AD5425 is a CMOS 8-bit current output digital-to-analog converter, 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. In addition, an LDAC (Active Low) pin is provided, which allows simultaneous update in multi DAC configuration. On power-up, the internal Shift register and Latches are filled with zeros and the DAC outputs are at 0 V.
As a result of processing on a CMOS sub micron process, this DAC offers excellent four quadrant multiplication characteristics, with large signal multiplying bandwidths of 10 MHz.
