ANALOG DEVICES’ 14-BIT A/D CONVERTERS MEET DEMANDING PERFORMANCE REQUIREMENTS OF COMMUNICATIONS, INSTRUMENTATION AND TEST AND MEASUREMENT APPLICATIONS

Analog Devices’ 14-bit A/D Converters Meet Demanding Performance Requirements of Communications

Norwood, MA (08/22/2011) - 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.

The AD9648 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 converter’s proprietary differential input maintains excellent SFDR performance for input frequencies up to 350 MHz.

AD9648 14-bit High-speed A/D Converter Key Features:

  • SNR = 74.5 dBFS at fIN up to 70 MHz at 125 MSPS
  • ENOB of 11.8 at fIN up to 70 MHz at 125 MSPS (−1.0 dBFS)
  • SFDR = −91 dBc at fIN up to 70 MHz at 125 MSPS (−1.0 dBFS)
  • Integrated input buffer
  • Excellent linearity
    • DNL = ±0.5 LSB typical
    • INL = ±1.0 LSB typical

AD9642 14-bit High-speed A/D Converter Key Features:

  • SNR = 70.9 dBFS at 200 MHz AIN and 250 MSPS
  • SFDR = 86 dBc at 200 MHz AIN and 250 MSPS
  • -152.0 dBFS/Hz input noise @ 200 MHz, -1dBFS AIN and 250 MSPS
  • Total power consumption: 360 mW @ 250 MSPS
