Analog Devices Press Release - November 10, 2011

Analog Devices Introduces Highly Integrated Octal and Quad ADCs for
Demanding Medical Imaging and Communications Applications

-- High-speed A/D Converters Feature More Channels, Lower Power and Smaller Package Size

AD9253 block diagramNORWOOD, Mass.--(BUSINESS WIRE)-- Analog Devices Inc. (ADI), a global leader in high-performance signal processing technology, announced today the addition of four high-speed A/D data converters to its market-leading data converter product portfolio. The two octal- and two quad-channel converters are designed for medical imaging and communications applications where the combination of high channel density, low power and small size provide systems engineers with greater design flexibility and lower per-channel cost for data conversion.

The AD9257 14-bit and AD9637 12-bit octal A/D converters each integrate eight A/D converters into one package and feature 40 percent lower power per channel than other discrete octal converters. Analog Devices today 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. Data Conversion for Medical Imaging
All of the new 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 an 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 VGA (variable gain amplifier) for ultrasound applications.

Data Conversion for Communications
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.
The ADL5202 variable gain wide bandwidth amplifier, AD8376 ultralow distortion IF dual VGA and ADA4937 ultralow distortion differential ADC driver work well with these high-speed converters in communications applications.

Key High Speed A/D Converter Features
  • Low ADC core power
  • Serial LVDS (ANSI-644, default)
  • Low power, reduced output swing option (similar IEEE 1596.3)
  • Data and frame clock outputs
  • Operates on a single 1.8-V power supply
  • 650-MHz full-power analog bandwidth
  • 2-V p-p input voltage range
  • Serial port control
  • Specified over the industrial temperature range of -40°C to +85°C
