Developed using a combination of innovative design processes and packaging techniques, Analog Devices' latest digital-to-analog converters (DACs)provide performance in smaller packages. Because of their compact size and low power consumption, these new nanoDACs provide advantages in space-constrained applications where power consumption is critical. The converters are aimed at voltage-level setting applications used in a wide range of communications, consumer and handheld battery-powered designs including digital cameras, projectors and PDAs.

Leading the nanoDAC family in a compact SC-70 package is the AD5641, which consumes 70 percent less board area and 80 percent less power than comparable devices. Delivering 14-bit resolution and guaranteed monotonic behavior with a maximum power consumption of 100 uA at 5 V, the AD5641 combines fine output control with low power in a compact footprint. In addition to the AD5641, Analog Devices is introducing the AD5621 (12 bits), AD5611 (10 bits), and AD5601 (8 bits). These lower resolution devices provide suitable alternatives for applications not requiring the performance of the AD5641.

The AD5641 is designed using a combination of Analog Devices' patented "segmented string" architecture, which offers accuracy in the smallest die area and patented advanced chip-on-lead (COL) die packaging technology. The string architecture is segmented in substrings to provide die size savings, while the COL assembly technology maximizes package cavity size and therefore minimizes the customer's board footprint.

The AD5641 (14 bits), AD5621 (12 bits), AD5611 (10 bits) and AD5601 (8 bits) are sampling now and will be available in production quantities in December 2004. Each part is available in 6-lead SC-70 packaging with 1K prices ranging from $0.95 to $4.75 depending on the resolution and accuracy combination
