Analog Devices unveiled what it claims are the industry's only multichannel DDS (direct digital synthesis) devices that provide a solution to two common design challenges faced by system engineers in a range of applications.
Allowing independent programming of up to four inherently synchronised outputs, ADI's four-channel AD9959 and two-channel AD9958 deliver better control to correct imbalances between multiple signals. This means is designers needn't spend as much time on this usually complex element of the system design. For space-constrained systems, the AD9958 and AD9959 simplify the design process by integrating multiple DDS channels on a single chip, eliminating the need for several single-channel DDS chips and external circuitry. As a result, board space can be reduced by up to 75% over traditional solutions.
