Texas Instruments introduces first quad-channel 16-bit, 100 MSPS ADC for faster, smaller medical imaging equipment

A non-magnetic package option allows for use in a strong magnetic field, such as in MRI machines.

“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:
o SNR of 84.6 dBFS with 10-MHz input and 100 MSPS sampling frequency.
o 380 mW/channel.
o 4-Vpp full-scale input.
· In low-power 14-bit mode, the ADS5263 cuts its power consumption by about half:
o SNR of 73 dBFS with 10 MHz input and 100 MSPS.
o 195 mW/channel.
o 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.
