Bangalore: Analog Devices, Inc. announced the dual-channel, 1.25-V,14-bit, 1-GSPS AD9680 analog to digital converter featuring the best noise and dynamic range performance in its class enabling the trend for direct RF Sampling in communications, instrumentation and military/aerospace applications. Its noise density of -154 dBFs/Hz is the lowest in the industry. The breakthrough performance, bandwidth and integrated functionality of ADI’s wideband RF data acquisition technology allows for better signal extraction in congested RF environments over a wider bandwidth than ever before. The AD9680 is interoperable with FPGAs from major manufacturers and supported with known good configurations. The AD9680 combined with the recently announced 12-bit, 2-GSPS AD9625 A/D converter; demonstrate ADI’s innovation in providing leading edge offerings driving the trend toward direct RF sampling.



Analog Devices, Inc. (NASDAQ: ADI) is a  data converter company that has innovation, performance, and excellence as the cultural pillars on which the organization is built and is one of the longest standing, highest growth companies within the technology sector. With services to industry as the world leader in data conversion and signal conditioning technology, the organization serves over 60,000 customers, representing virtually all types of electronic equipment. The has the history of  over 40 years as a leading global manufacturer of high-performance integrated circuits used in analog and digital signal processing applications.



The newly launched AD9680 analog to digital converter allows better breakthrough performance, bandwidth, integrated functionality drive applications to direct RF sampling with degrees of freedom for system designers trading off signal bandwidth, noise and linearity because it can digitize a DC to 2-GHz input signal with an accompanying dynamic range performance that was unavailable on the open market. With AD9680, engineers can increase signal sensitivity and bandwidth data rate, while enabling the use of an advanced reconfigurable data acquisition or radio platform. The A/D converter is available with an evaluation board design environment and reference designs for rapid system prototyping and board-level design and layout.



The AD9680 was designed for sampling wide bandwidth analog signals up to 2 GHz and features the industry’s best dynamic range and noise performance at its rated bandwidth range. When converting a 1-GHz input, the converter achieves spurious-free dynamic range (SFDR) performance of 80-dBc and 61.5-dBFS signal-to-noise ratio (SNR) while consuming 1.65 W of total power per channel. Providing buffered inputs with programmable input termination eases filter design and implementation.



Each GSPS Analog to Digital converter is supported by an evaluation board with an FPGA Mezzanine Card (FMC) connector, software, tools, SPI controller and reference designs. ADI’s VisualAnalog software package combines a powerful set of simulation and data analysis tools with a user-friendly graphical interface allowing designers to customize their input signal and data analysis.
