Analog Devices introduced direct digital synthesis (DDS) ICs that offer 30 percent lower power consumption and a 60 percent reduction in footprint than competing devices while operating over the extended temperature range of 40º C to 125º C.

The AD9838 DDS and AD9837 DDS ICs consume as little as 11 mW when operating from clock rates up to 16 MHz. The new devices are well suited for industrial and communications applications, including sensory excitation, impedance spectroscopy and battery-enabled diagnostic and communication equipment.

AD9838 DDS and AD9837 DDS ICs Feature Small Package Size

* The small package size of the AD9838 DDS (4 mm × 4 mm) and AD9837 (3 mm × 3 mm) DDS ICs allows developers to reduce the footprint of their designs or increase sensor-node density to enable the development of feature-rich applications within the same form factor.
* Low-power performance enables engineers to generate high-performance sine, square, and triangular outputs to meet the low-power consumption targets of battery-operated equipment or include advanced features within existing power budgets.
* Integration of various communication and modulation features enables the devices to support single-tone, 2FSK, 2PSK, QPSK, sweep capability and amplitude modulation, simplifying the design of communication systems and reducing development risk and cost.
* High spectral performance (greater than 68-dB wideband SFDR) enables product developers to keep pace with evolving needs in instrumentation and communication equipment.
