Low power 12bit ADC consumes 660 MW at 500 MSPS

Analog Devices, Inc. has introduced ADC IC, the AD9434, a low-power, 12-bit, 500-MSPS (mega samples per second) converter which reduces thermal considerations by consuming 660 mW of power in a space-saving 8 mm x 8 mm LFCSP package. Analog Devices has also made available is an 8-bit, pin-compatible version, the AD9484 A/D converter.

With 65-dBFS SNR (signal-to-noise ratio) up to a 250-MHz input frequency at 500 MSPS, the AD9434 A/D converter is designed to meet 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.

AD9434 12-bit A/D Converter Key Features:

Low power dissipation: 660 mW at 500 MSPS
10.5 ENOB up to 250 MHz at 500 MSPS
78 dBc SFDR up to 250 MHz at 500 MSPS
