Quad channel 16-bit ADC from TI delivers SNR of 84.6 dBFS

Texas Instruments Incorporated has introduced quad-channel, 16-bit analog-to-digital converter (ADC) for medical imaging applications, such as magnetic resonance imaging (MRI). TI say 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. This ADC consumes a low power of 380 mW/channel and is packaged in small footprint .A non-magnetic package option allows for use in a strong magnetic field, such as in MRI machines.

ADS5263 can switch between 14 and 16 bit resolution modes to operate in either Low power of high speed mode.

"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."

In addition to medical imaging systems, the ADS5263 is also suggested for industrial instrumentation applications.
