ADS5263 - first quad-channel 16-bit, 100 MSPS ADC for faster, smaller medical imaging equipment
/ contains 1x video / Texas Instruments Incorporated 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

“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.
