TI has introduced the first quad-channel, 16-bit analog-to-digital converter (ADC) for medical imaging applications, such as magnetic resonance imaging (MRI)

Texas Instruments (TI) has introduced the first quad-channel, 16-bit A/D converter for medical imaging applications such as magnetic resonance imaging (MRI).

The ADS5263 delivers 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: www.ti.com/ads5263-pr

“Medical imaging systems like MRI machines 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. 




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:      
* In low-power 14-bit mode, the ADS5263 cuts its power consumption by about half:     
* 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.

The ADS5263 is the latest addition to TI’s extensive line of highly optimized analog products for medical imaging systems and other medical applications.  The company's portfolio of semiconductor solutions for medical applications includes embedded processors, such as DSPs and MCUs, plus a full range of analog signal chain, power management and wireless connectivity solutions, which allow manufacturers to bring innovative

medical electronics to market faster.
