Analog Devices, a global provider of high-performance semiconductors for signal processing applications, today introduced the industry's fastest 16-bit digital-to-analog converter (DAC) with a conversion rate exceeding 600 MSPS. In addition, this device also features unprecedented noise performance: -161 dBm/Hz for output frequencies between 100 MHz and 300 MHz and -169 dBm/Hz at 20-MHz output. This combination of high speed and low noise is ideal for maximizing signal synthesis performance in multi-carrier communication systems, as well as in instrumentation and test applications. The DAC also solves noise and bandwidth challenges by reducing intermodulation distortion (IMD), thus enabling higher quality signal synthesis and higher speed information processing.
Analog Devices' new 16-bit AD9726 joins the company's industry-leading TxDAC+(R) portfolio of converters. These high-speed transmit DACs are designed to meet demanding communication system requirements. The AD9726 is the flagship member of a new AD972x family of 10-, 12-, 14- and 16-bit TxDAC+ converters that sample at 600 MSPS and provide a fast low voltage differential signaling (LVDS) input interface. The LVDS inputs enable high conversion rates and bandwidth, allowing the devices to receive data at a high speed, while maintaining low distortion and noise. The AD972x family also provides a component selection path based on resolution, performance and cost.
"Designers of communication and instrumentation systems striving to achieve the highest possible performance are turning to faster, higher resolution converters," said Kevin Kattmann, product line director for high-speed converters, Analog Devices. "Once again, Analog Devices has drawn on its lineage of innovation in high-speed conversion to set the industry standard for speed and performance. Our LVDS technology is enabling extremely high sampling rates, and in the near future, converters capable of sampling beyond 1 GSPS will become a reality."
The AD9726 is ideal for use in high-frequency, high-bandwidth broadcasting and communications applications, such as MMDS (multipoint multichannel distribution service), and LMDS (local multipoint distribution system). These applications benefit from the part's ability to produce wide bandwidth signals with low noise and distortion. The AD9726 also is appropriate for test and measurement equipment, instrumentation, radar, and satellite communications systems.
The 16-bit AD9726 LVDS receivers support SDR (single data rate) or DDR (double data rate) modes. The part contains a flexible timing interface that simplifies use and system design. Its wide bandwidth allows more information to be transmitted and the combination of the device's low noise and low distortion provide higher quality transmission. The device's IMD is less than -80 dBc up to a 300 MHz output frequency, reducing signal processing errors.
A wide full-scale current adjustment span of 2 mA to 20 mA allows the AD9726 to operate at reduced power levels. The current outputs of the part can be easily configured for various single-ended or differential circuit topologies.
