Analog – Low-power 12-bit 1.8V A/D converter consumes only 660mW at 500MSPS (AD9434)Apr 28 2011 - Semiconductors [More Semiconductors Articles]
New data converters, designed to deliver the speed and performance, at low power, necessary for a range of communications and industrial applications, have been unveiled by Analog Devices (ADI).
With 65-dBFS SNR (signal-to-noise ratio) up to a 250MHz input frequency at 500 MSPS, the AD9434 A/D converter meets the low power, small size, and high dynamic range requirements needed for communications infrastructure, radar systems, data acquisition systems and test and measurement applications. The AD9434 A/D converter also is pin-compatible with ADI’s AD9230 12-bit, 250-MSPS A/D converter to allow for easy substitution with minimal design changes in many applications.
The AD9434 provides a complete signal conversion solution with sample-and-hold, voltage reference, LVDS outputs, a single 1.8-V supply and integrated data clock output with programmable clock included on the component. The LVDS digital output data and output-clock timing interface are programmable to provide flexibility with today’s FPGA (field-programmable gate array) products.
Housed in a 56-lead LFCSP 8mm x 8mm package, the AD9434 A/D converter can be designed into circuits for communications applications with ADI’s AD9523/24 low-jitter clock generator and ADL5562 ultra-low-distortion RF/IF differential amplifier, says the company.
