AD5679R DAC Evaluation Board ACE Software IDE
With the AD5674/AD5674R/AD5679/AD5679R family, Analog Devices has created a 2x higher channel density than current 8-channel parts in the same 4x4 LFCSP footprint. This also eases the customer design-in experience, reducing the number of decoupling capacitors needed and general layout simplification.
The devices operate from a single, 2.7 V to 5.5 V supply range and are guaranteed monotonic by design. The AD5674/AD5674R/AD5679/AD5679R are available in a 28-lead lead frame chip scale package (LFCSP) and incorporate a power-on reset (POR) circuit that ensures that the DAC outputs power up to and remains at zero-scale or midscale until a valid write. The AD5674/AD5674R/AD5679/AD5679R contain a power-down mode that reduces the current consumption to 2 ฮผA typical.
