INDUSTRY’S FIRST 256-CHANNEL, 24-BIT CURRENT-TO-DIGITAL CONVERTER MODULE FOR CT SCANNERS SIMPLIFIES DESIGN AND REDUCES SYSTEM COSTS

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.
Industry’s First 256-Channel, 24-Bit Current-to-Digital Converter Module for CT Scanners Simplifies

Norwood, MA (07/30/2014) - 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.
