Analog Devices' 14-Bit A/D Converters Meet Demanding Performance Requirements of Communications, Instrumentation And Test Measurement Applications.

The is a low-power, high-speed, 14-bit dual A/D converter that consumes 102 mW/channel at 125 MSPS (mega samples per second) and features SFDR (spurious-free dynamic range) performance of 91 dBc at 70 MHz. With IF sampling frequencies up to 200 MHz, the AD9648 is a good choice for designers looking for a dual high-speed A/D converter to build multimode digital receivers. The AD9648 is pin compatible with many of ADI’s 16-, 14-, 12- and 10-bit A/D converters, enabling an easy migration path between 10-bit and 16-bit converters sampling from 20 MSPS to 125 MSPS.

Analog Devices released the AD9642 14-bit A/D single-channel converter. With a 5 mm x 5 mm package size -- 30 percent smaller than competing products -- and IF sampling frequencies up to 350 MHz, the AD9642 saves board space and supports wide bandwidths up to 125MHz. It features an SNR (signal-to-noise ratio) of 72.2 dBFS and SFDR of 90 dBc at base band, while consuming only 360 mW at 250 MSPS.
