New DACs use advanced design techniques to enable breakthrough performance in low-power, space-constrained applications.
April 27, 2004 - Analog Devices, Inc. introduced the first members of its new nanoDACTM family of digital-to-analog converters which provide breakthrough performance in smaller packages. Because of their compact size and low power consumption, these new digital-to-analog converters (DACs) provide significant advantages in space-constrained applications where power consumption is critical. Developed using a combination of innovative design processes and packaging techniques, the converters are ideal for 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 nanoDACTM family's product offerings is the world's smallest, low-power D/A converter. Available in a compact SC-70 package, the AD5641 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 volts, the AD5641 combines fine output control with low power in a compact footprint. The combination of small package and low power consumption make the AD5641 ideal for voltage level setting requirements such as generating bias or control voltages in space-constrained low power wireless applications, including cell phone volume controls and screen lighting.
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.
Pricing and availability
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.
