Current-to-Digital Converter Module simplifies CT scanner design.

Press Release Summary:

Current-to-Digital Converter Module simplifies CT scanner design.

Aug 04, 2014 - Reducing complexity of CT scanner system design, ADAS1131 embeds 256 integrators, simultaneous sample-and-hold circuitry, and 2 high-speed ADCs with configurable sampling rates. Module also incorporates all associated internal buffers as well as decoupling and by-pass capacitors for data acquisition. With 0.8 mm pitch, 15 mm² BGA package can be mounted on standard PCB substrate. This 256-channel, 24-bit current-to-digital converter module consumes 3 mW per channel at any throughput.

Industry's First 256-Channel, 24-Bit Current-to-Digital Converter Module for CT Scanners Simplifies Design and Reduces System Costs

Press release date: Jul 30, 2014

ADI’s new current-to-digital converter module doubles channel count while requiring 33 percent less real estate than alternative devices, plus mounts on standard PCB substrates.

NORWOOD, Mass. -- Analog Devices, Inc. (NASDAQ: ADI), a global leader in high-performance signal processing technology and leading provider of ICs for medical imaging, introduced today a current-to-digital converter module that reduces the cost and complexity of computed tomography (CT) scanner system design. The ADAS1131 is a 256-channel, 24-bit current-to-digital converter module that is available in a 15-mm² BGA package with a 0.8-mm pitch. The device uses approximately 33 percent less PCB area than alternative devices that offer only half the channel density. The 0.8-mm pitch packaging feature enables designers to mount the ADAS1131 on a standard PCB substrate, a less costly and higher yield option than high density, specialized PCB substrates requiring laser vias.

In addition to embedding 256 low-power, low-noise, low-input-current integrators, simultaneous sample-and-hold circuitry, and two high-speed A/D converters with configurable sampling rates, the ADAS1131 module incorporates all associated internal buffers, decoupling and by-pass capacitors for data acquisition, further reducing component count and simplifying board layout. The new converter consumes 3 mW of power per channel at any throughput, which is the same as competing devices that integrate only 128 channels.
