Analog Devices' 14-bit A/D Converters Meet Demanding Performance Requirements of Communications,
Instrumentation and Test and Measurement Applications
NORWOOD, Mass.--( BUSINESS WIRE)-- Analog Devices Inc. (ADI), a global leader in high-performance signal processing technology, 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.
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.
Also today, 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.

The AD9648 and AD9642 A/D converters feature
multi-stage, differential pipelined architectures with integrated output-error-correction logic. The AD9648 is
available in a 64-lead RoHS-compliant LFCSP, while the AD9642 ships in a 32-lead RoHS-compliant LFCSP package.
Both are specified over the industrial temperature range of -40°C to +85°C. The AD9648 has two external 14-bit
outputs that can be set to 1.8-V CMOS or LVDS. The AD9642’s proprietary differential input maintains excellent
SFDR performance for input frequencies up to 350 MHz.
