The DAC5681Z is a 16-bit 1.0 GSPS digital-to-analog converter (DAC) with wideband LVDS data input, integrated 2x to 4x interpolation filters, on-board clock multiplier, and internal voltage reference. The DAC5681Z offers superior linearity, noise, crosstalk, and PLL phase noise performance.
●The DAC5681Z integrates a wideband LVDS port with on-chip termination. Full-rate input data can be transferred to a single DAC channel, or half-rate and 1/4-rate input data can be interpolated by on-board 2x or 4x FIR filters. Each interpolation FIR is configurable in either low-pass or high-pass mode, allowing selection of a higher order output spectral image. An on-chip delay lock loop (DLL) simplifies LVDS interfacing by providing skew control for the LVDS input data clock.
●The DAC5681Z is characterized for operation over the industrial temperature range of 40°C to 85°C and is available in a 64-pin VQFN package. Other members of the family include the dual-channel, interpolating DAC5682Z and the single-channel, non-interpolating DAC5681.
