DALLAS, May 23, 2011 /PRNewswire/ -- Texas Instruments
Incorporated (TI) (NYSE: TXN) today introduced the first
quad-channel, 16-bit analog-to-digital converter (ADC) for medical
imaging applications, such as magnetic resonance imaging (MRI). The
ADS5263 meets designers' needs for clear, crisp signals and faster
acquisition times by delivering a high signal-to-noise ratio (SNR)
of 84.6 dBFS with 10-MHz input and a sampling frequency of up to
100 MSPS. Along with high performance, the quad-channel
architecture, low power consumption of 380 mW/channel and
small footprint of the ADS5263 allow engineers to design smaller,
more compact medical imaging systems than were previously possible
with existing single- or dual-channel devices. A non-magnetic
package option allows for use in a strong magnetic field, such as
in MRI machines [view video]. For information, samples and EVMs:

"Medical imaging systems like MRI machines typically require
numerous high-performance electronics to achieve the clear,
high-contrast images that doctors use for early detection of
diseases. The large machines often involve a lengthy scan process,
during which the patient is required to lie completely still," said
Steve Anderson, senior vice
president of TI's High Performance Analog business unit. "Taking
advantage of both our data converter expertise and our
long-standing experience in medical imaging applications,
manufacturers can use the performance and compact footprint of the
ADS5263 to deliver smaller, faster equipment with outstanding image
quality for more efficient scans and increased patient
comfort."
Key features and benefits:
- 14- and 16-bit resolution modes allow designers to switch
between low-power and high-speed, high-resolution operation.
- In 16-bit mode, the ADS5263 delivers crisp images while
maintaining low power consumption:
- SNR of 84.6 dBFS with 10-MHz input and 100 MSPS sampling
frequency.
- 380 mW/channel.
- 4-Vpp full-scale input.
- In low-power 14-bit mode, the ADS5263 cuts its power
consumption by about half:
- SNR of 73 dBFS with 10 MHz input and 100 MSPS.
- 195 mW/channel.
- 2-Vpp full-scale input.
- Compact footprint: Quad-channel architecture in 9-mm x 9-mm QFN
package uses 50-percent less board space than existing single- or
dual-channel devices.
- Non-magnetic package option allows for operation without image
distortion in a strong magnetic field, such as in MRI
equipment.
- In addition to medical imaging systems, the ADS5263 brings the
same benefits to industrial instrumentation applications.
Tools and support
To provide a flexible environment for testing the ADS5263 under
a variety of conditions, an evaluation module (EVM) is available.
The ADS5263EVM is priced at $299.
An IBIS model to verify board signal integrity requirements is
also available.
Availability, packaging and pricing
The ADS5263 is available now in two 9-mm x 9-mm QFN package
options. The regular package for high-resolution, high-speed
medical and industrial applications without a magnetic field is
priced at $236.50 in quantities of
1,000. The non-magnetic package option for applications with a
magnetic field, such as MRI machines, is priced at $385.50 in quantities of 1,000.
