Norwood, MA (10/19/2010) - Analog Devices, Inc. (ADI), a world leader in semiconductors for high-performance signal processing applications and leading supplier of signal conditioning technology, introduced today low-power, low-noise drivers for 14-bit ADCs (analog-to-digital converters). The ADA4930-1 and ADA4930-2 ultra-low-noise ADC drivers are capable of driving dc to 1.35-GHz signals while consuming only 115 mW (milliWatts) of power and operating with a single supply.
The new ADC drivers feature one of the industry’s lowest noise specification of 1.2 nV/rt-Hz and low distortion in the frequency range of 20 MHz to 100 MHz. The combination of low noise and low distortion ensures more accurate measurement and signal representation for 14-bit ADCs used in electronic test and measurement equipment, data acquisition systems, wireless direct-conversion receivers and other wideband applications with data throughput of 40 MSPS (million samples per second) to 200 MSPS.
The ADA4930-1 and ADA4930-2 ultra-low-noise ADC drivers feature a 0.9-V output common mode voltage and are ADI’s first single-supply ADC drivers capable of driving the input of a dc-coupled, 1.8-V ADCs all the way to ground. This eliminates the second voltage supply required by other ADC drivers and reduces cost, power use and board space. The ADA4930-2 dual-channel ADC driver works well with ADI’s AD9640 dual ADC, while the ADA4930-1 single-channel ADC driver is suited to operate with ADI’s AD9255 single ADC.
“The ADA4930 ADC driver offers one of the lowest input-voltage noise specifications of any high-frequency ADC driver at a third less power consumption than competing products,” said Jim Doscher, product line director, High Speed Linear Products, Analog Devices. “For analog circuit designers who need dc-coupled ADC signal paths for their high-frequency designs, the ADA4930 series drives high fidelity signals at a much wider bandwidth than competing devices, while removing the need for a second power supply.”
