NORWOOD, Mass.--(BUSINESS WIRE)--July 29, 2002

- Industry's first 14-bit ADC with sub-600 mW power consumption reduces costs of wireless and imaging signal processing systems.

Analog Devices, Inc. (NYSE:ADI), a global leader in high-performance semiconductors for signal processing applications and the market share leader in data converters, today announced a new advanced CMOS data converter that provides the excellent performance typical of bipolar-process converters while achieving 55 percent lower power consumption than comparable, available converters. The AD9244 analog-to-digital converter (ADC) provides 14-bits of accuracy at a speed of 65 million samples per second (MSPS) while consuming only 590 milliwatts (mW) of power.

The AD9244 permits cost-effective IF sampling system architectures in wireless base stations by supporting frequencies as high as 200 MHz, eliminating a down-conversion stage, reducing parts count, and ultimately lowering the cost and improving the overall reliability of the basestation. The 590 mW power consumption makes the AD9244 well-suited to pico-cell and micro-cell designs with multiple base stations on one tower or location--helping to improve cellular coverage in highly-populated regions--and high-end imaging and ultrasound applications that require top performance and low power dissipation. The AD9244 is also available in a 40 MSPS version, further lowering power dissipation to 345 mW.

"Wireless infrastructure manufacturers and carriers are looking to reduce cost in every design, as they drive adoption of next generation wireless standards," said Kevin Kattmann, product line director for High-Speed Converters, Analog Devices. "The AD9244 delivers a breakthrough in power and performance that goes straight to the bottom line--a lower bill of materials cost for manufacturers and lower power costs for carriers--and improves system reliability. Its market leading power dissipation and cost-efficiency makes the AD9244 attractive to businesses looking to develop new solutions in wireless communication and high-end imaging applications."

About the AD9244

The AD9244 uses a multi-stage differential pipelined architecture with output error correction logic to provide 75 dB SNR, 90 dB SFDR and 14-bit accuracy at 65 MSPS. It guarantees no missing codes over the full operating temperature range. It is pin-compatible with the AD9226 12-bit 65 MSPS ADC, providing a simple migration path to 14-bits of resolution.

An evaluation board that facilitates quick bench trials and simplifies final circuit design is available. The ADC Analyzer(TM) software allows designers to capture and display multiple waveforms in graphical form, perform FFT calculations, and measure SNR, THD, and SFDR.

Pricing and Availability

The AD9244 is available in a 48-pin LFQP package. The 40-/65-MSPS versions are priced at $20.00/$29.00 per unit in 1,000-piece quantities. Samples and evaluation boards are available now. Production quantities will be available in August. For more information, please visit http://www.analog.com/AD9244
