Analog Devices Inc. (ADI) expanded its market-leading data converter product portfolio by announcing the addition of four high-speed A/D data converters. These A/D converters offer a variety of channel densities, sampling rates, and packaging options.

The two octal- and two quad-channel converters are targeted at medical imaging and communications applications where combining high channel density, low power and small size.

The AD9257 14-bit and AD9637 12-bit octal A/D converters each integrate either A/D converters into one package and feature 40 percent lower power per channel than other discrete octal converters. Analog Devices also introduced the AD9253 14-bit and AD9633 12-bit quad A/D converters in 48-lead chip-scale packages that are more than 10 percent smaller than competing devices.

All converters support the higher channel densities of MRI (Magnetic resonance imaging) systems, medical ultrasound and other high-end imaging applications, such as industrial visual inspection systems and non-destructive ultrasound. The AD9253 14-bit and AD9633 12-bit quad A/D converters are offered in a non-magnetic package and can be used safely within the magnetic field of a MRI system. This allows the converters to be placed closer to the signal of interest, which can increase the quality of image resolution and image throughput while reducing the overall component count.

Complementary components for these high-speed converters include the AD8334 quad, ultralow noise VAG (variable gain amplifier) for ultrasound applications.

The new octal and quad A/D converters are also suited to MIMO-based (multiple-input, multiple-output) radios, 3G infrastructure equipment and other wireless communications applications.
