One of the primary applications of the DACx1416 family is Mach Zehnder Modulator (MZM) biasing, employed in Optical Line Cards and Optical Modules. With high-voltage, high-current and differential output features, the DACx1416 family can be used for biasing both LiNbO₃ and InP type modulators. With the help of the toggle mode and multiple corresponding input pins, the required dither waveform for such applications can be generated without involving SPI programming. The small package size and integrated reference minimize the total footprint of such applications.
