Analog Devices announced the AD9653 four-channel high-speed ADC. The AD9653 is a quad, 16-bit, 125 MSPS analog-to-digital converter. It features an on-chip sample-and-hold circuit designed for low cost, low power, small size, and ease of use. The product operates at a conversion rate of up to 125 MSPS and is optimized for high performance and low power in applications where a small package size is critical. The AD9653-125 (77.5 dBFS @ 70 MHz, 125 MSPS) is available now in a 48-pin LFCSP non-magnetic package (PB-free). It is priced at $250 each in 1,000 units quantities.
The AD9653 16-bit quad A/D converter supports the higher channel densities of MRI (magnetic resonance imaging) systems, medical ultrasound and other high-end imaging applications, such as industrial visual inspection systems and non-destructive ultrasound. It is offered in a non-magnetic package and can be used safely within the magnetic field of an MRI system. This allows the converter to be placed closer to the signal of interest, which can increase the image quality and throughput while reducing the overall component count.
