Breakthrough performance improvements position the AD9226 as a

premier 12-bit IF-Sampling ADC solution.

Analog Devices, Inc. (NYSE:ADI) today introduced the AD9226, a 12-bit, 65 MSPS analog-to-digital converter that simplifies system design, increases data rates, and enables economical direct IF-sampling architectures for communications applications, such as next-generation cellular base station and software radio applications.

"The pressure within the wireless communications industry to continually reduce the size, cost, and efficiency of base station technology created the demand for a new class of A/D converters with high dynamic range at wide input bandwidths," said Jon Hall, marketing manager for the High-Speed Converter Group at Analog Devices. "The AD9226 represents the next generation of this class of A/D converter. It enables direct IF under-sampling in software radio applications, thus simplifying communications system design, and significantly lowering overall system costs."

Key to the AD9226's appeal is its ability to digitize wideband signals with ENOB (effective number of bits) performance greater than 11 bits. The AD9226 dissipates 475 mW of power from a +5V single supply. Its 750 MHz full-power input bandwidth, pin-compatibility with family AD922X products and on-chip sample/hold amplifier, clock duty cycle stabilizer and out-of-range indicator comprise the AD9226's attributes.

Applications include next-generation wired and wireless communications, base stations, wireless local loop, radar and high-speed instrumentation where demodulation and signal tuning/filter functions are accomplished in the digital domain. A single AD9226 allows IF transceivers to be re-programmed immediately to accommodate multiple modulation formats, thus reducing complex hardware requirements. This approach requires direct digitization at the higher IF frequency where the AD9226's "IF-ready" input architecture can digitize a 70 MHz IF signal with 86.4 dB of spurious free dynamic range performance.

The AD9226 is priced at $18.55 in 1,000-piece quantities with production quantities available from stock to fuel the industry's transition to direct IF under-sampled architectures. The AD9226 is specified for operation from -40(0)C to +85(0) C and is available in either 28-lead shrink small outline or 48-lead LQFP packages.
