Texas Instruments Introduces the ADS5263, the First Quad-Channel, 16-Bit ADC for Medical Imaging Applications

Texas Instruments Incorporated introduced the ADS5263, 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.

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.

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.
