Analog Devices ( www.analog.com ), a global specialist in data converters for signal processing and high-performance semiconductors, announced a dual 16-bit 105 MSPS (Mega Samples Per Second) low-power, low-noise ADC (Analog-to-Digital Converter) for high-performance data acquisition systems such as medical imaging, industrial, spectrum analysis, multimode radio, and radar applications.

“Today, customers are demanding high-resolution image capture capabilities that can improve the diagnostic performance of medical imaging devices,” said Patrick O’Doherty, Vice President of Healthcare at Analog Devices. “With the AD9650, medical device designers can increase the density of image channels while enabling low-noise, low-power designs, thereby meeting customer requirements.”

The AD9650 ADC consumes 328mW per channel, which is half the power consumption of comparable competitor data converters, while boasting an industry-leading Signal-to-Noise Ratio (SNR) of 82dBFS and a Spurious-Free Dynamic Range (SFDR) of 90dBc at a 30MHz input. Furthermore, by utilizing the on-chip dither function, enhanced SFDR characteristics can be achieved even with low-level analog input signals, providing implementation flexibility to engineers who wish to use proprietary differential inputs within a frequency range of up to 300MHz.

The AD9650 ADC, supplied in a compact 9mm x 9mm package, is pin-compatible with Analog Devices’ AD9268 16-bit 125 MSPS, AD9251 14-bit 80 MSPS, and AD9269 16-bit 80 MSPS dual ADCs, allowing system engineers to improve the performance of data acquisition systems without changing the board layout.

The AD9650 operates with a single 1.8V power supply and a separate digital output driver power supply, and provides 1.8V CMOS or LVDS output. Additionally, the AD9650 is available in various speed classes of 80 MSPS, 65 MSPS, and 25 MSPS. More detailed information about the AD9650 can be found at http://www.analog.com/pr/AD9650 .
