Analog Devices ( www.analog.com ), a global leader in signal processing data converters and high-performance semiconductors and a leader in the global data converter market, announced today low-power, low-noise drivers (product names: ADA4930-1, ADA4930-2) for 14-bit Analog-to-Digital Converters (ADCs).

The ADA4930 ultra-low noise ADC driver, which provides an output common-mode voltage of 0.9 V, is Analog Devices' first single-power ADC driver capable of driving a DC-coupled 1.8 V-ADC input down to ground level, eliminating the need for an auxiliary power supply and saving on cost, power consumption, and board space.

In addition, it features a single power supply and low power consumption of 115 mW, while enabling signal driving in the DC to 1.35 GHz range and providing the industry's lowest noise specification of 1.2 nV/rt-Hz and low distortion characteristics in the 20 MHz to 100 MHz frequency range. This improves the measurement and signal representation accuracy of 14-bit ADCs used in broadband applications with data throughput ranging from 40 MSPS (Million Samples Per Second) to 200 MSPS, including electronic test and measurement equipment, data acquisition systems, and wireless direct conversion receivers.

Jim Doscher, Director of Analog Devices’ High-Speed Linear Products business unit, stated, “The ADA4930 ADC driver boasts power consumption that is only one-third of that of competitors and the lowest input voltage noise specifications among currently available high-frequency ADC drivers.” He added, “For design designers requiring DC-coupled ADC signal paths, the ADA4930 series appears capable of driving wide bandwidth and high-fidelity signals.
