• 500 MSPS

The DAC5687 is a dual-channel 16-bit high-speed

digital-to-analog converter (DAC) with integrated 2

• Full IQ Compensation Including Offset, Gain,

IQ compensation, and on-chip voltage reference. The

Even/Odd Multiplexed Input

The DAC5687 has six signal processing blocks: two

filter, and a coarse frequency mixer with fS/2 or fS/4.

The different modes of operation enable or bypass
