Analog Devices Inc., a global leader in high-performance
signal processing technology, introduced today the addition of a 4-channel
high-speed A/D converter to its market-leading data converter product
portfolio. The AD9653 A/D converter is 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 AD9653 16-bit A/D converter
joins previously-released 12-bit and 14-bit versions to form a pin-compatible,
power- and size-optimized series of high-speed converter products.
The AD9653 16-bit quad A/D converter supports 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. It is offered in a
non-magnetic package and can be used safely within the magnetic field of an MRI
system. This allows the converter to be placed closer to the signal of
interest, which can increase the image quality and throughput while reducing
the overall component count.
Complementary components for the AD9653 in MRI applications
include the ADL5202 variable gain, wide bandwidth amplifier, and the ADA4937 or
ADL5562 ultra-low-distortion differential A/D converter driver.
