The DAC5687 is a dual-channel 16-bit high-speed digital-to-analog converter (DAC) with integrated 2×, 4×, and 8× interpolation filters, a complex numerically controlled oscillator (NCO), onboard clock multiplier, IQ compensation, and on-chip voltage reference. The DAC5687 is pin-compatible to the DAC5686, requiring only changes in register settings for most applications, and offers additional features and superior linearity, noise, crosstalk, and PLL phase noise performance.
