Texas Instruments has introduced a quad-channel, 16-bit analog-to-digital converter (ADC) for medical imaging applications, such as magnetic resonance imaging (MRI). According to the company, it’s the first of its kind to meet these specs. The ADS5263 delivers a signal-to-noise ratio (SNR) of 84.6 dBFS with 10-MHz input and a sampling frequency of up to 100 MSPS. The quad-channel architecture, low power consumption of 380 mW/channel, and small footprint 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.

Other features of the ADS5263 include 14- and 16-bit resolution modes that allow designers to switch between low-power and high-speed, high-resolution operation, and a 9- by 9-mm QFN package.

The regular package for high-resolution, high-speed medical and industrial applications without a magnetic field is priced at $236.50 in quantities of 1000. The non-magnetic package option is priced at $385.50, also in quantities of 1000. 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.
