The DAC5687 is a dual-channel 16-bit high-speed digital-to-analog converter (DAC) with integrated 2x, 4x, and 8x interpolation filters, a complex numerically controlled oscillator (NCO), on-board 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. The DAC5687 has six signal processing blocks: two interpolate by two digital filters, fine frequency mixer with 32-bit NCO, a quadrature modulation compensation block, another interpolate by two digital filter and a coarse frequency mixer with Fs/2 or Fs/4. The different modes of operation enable or bypass the signal processing blocks.
