Analog Devices has announced four high-speed ADCs to its data converter product portfolio. The two octal- and two quad-channel converters are designed for medical imaging and communications applications. The AD9257 14bit and AD9637 12bit octal ADCs each integrate eight ADCs into one package and feature low power, says the company.
All converters support the high channel densities of MRI systems, medical ultrasound and high-end imaging applications, such as industrial visual inspection systems and non-destructive ultrasound. The AD9253 14bit and AD9633 12bit quad ADCs are available in a non-magnetic package and can be used safely within the magnetic field of an MRI system. This allows the converters to be placed closer to the signal of interest, which can increase the quality of image resolution and image throughput, claims the company. Complementary components for these high-speed converters include the AD8334 quad, low noise VGA for ultrasound applications.
The octal and quad ADCs are also suitable for multiple-input, multiple-output-based radios, 3G infrastructure equipment and wireless communications applications. The ADL5202 variable gain wide bandwidth amplifier, AD8376 distortion IF dual VGA and ADA4937 distortion differential ADC driver are compatible with these high-speed converters in communications applications.
The ADCs feature low ADC core power, serial LVDS, low power and reduced output swing option which is similar to IEE 1596.3, and data and frame clock outputs. They operate on a single 1.8V power supply and are work from -40 to +85°C. The ADCs also feature 650MHz full-power analogue bandwidth and 2Vpp input voltage range. They have a serial port control.
The octal ADCs are available in 9x9mm 64-lead LFCSP (lead-frame chip scale package). The quad ADCs are available in 7x7mm 48-lead LFCSP.
