The DAC5681 is a 16-bit 1.0 GSPS digital-to-analog converter (DAC) with wideband LVDS data input and internal voltage reference. The DAC5681 offers superior linearity and noise performance.
The DAC5681 integrates a wideband LVDS port with on-chip termination, providing full 1.0 GSPS data transfer into the DAC and lower EMI than traditional CMOS data interfaces. An on-chip delay lock loop (DLL) simplifies LVDS interfacing by providing skew control for the LVDS input data clock.
The current-steering architecture of the DAC5681 consists of a segmented array of current sinking switches directing up to 20mA of full-scale current to complementary output nodes. An accurate on-chip voltage reference is temperature-compensated and delivers a stable 1.2-V reference voltage. Optionally, an external reference may be used.
The DAC5681 is characterized for operation over the industrial temperature range of –40°C to 85°C and is available in a 64-pin QFN package. The device is pin upgradeable to the other members of the family: the DAC5681Z and DAC5682Z. The single-channel DAC5681Z and dual-channel DAC5682Z both provide optional 2x/4x interpolation and a clock multiplying PLL.
