Analog Devices has introduced two new data converters designed to deliver the speed and performance at low power necessary for a range of communications and industrial applications. The AD9434, a 12-bit, 500 MSps (mega samples per second) A/D converter, reduces thermal considerations by consuming only 660 mW of power in a space-saving 8 x 8 mm LFCSP package. Also available is an 8-bit, pin-compatible version – the AD9484.
With 65 dBFS SNR (signal-to-noise ratio) up to a 250 MHz input frequency at 500 MSps, the AD9434 meets the requirements for communications infrastructure, radar systems, data acquisition systems and test and measurement applications. The chip 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 onboard. The LVDS digital output data and output-clock timing interface are programmable to provide flexibility with today’s FPGA (field-programmable gate array) products.
