Analog Devices released today new single- and dual-channel 14-bit high-speed A/D converters. With high speed and high accuracy, the compact, cost-effective and functionally flexible components are effective for use in communications, instrumentation and test and measurement applications. The new converters meet the performance and small size requirements of the latest 3G and 4G multi-standard cellular infrastructure equipment such as CDMA2000, WB-CDMA, LTE, TD-SCDMA and multi-carrier GSM. Other applications include battery-powered, hand-held instruments, scopes and portable medical devices.

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.
