16bit dual adc uses half power of competing data converters says ADI

The AD9650 dual 16bit 105 mega samples per second (ms/s), low power, low noise analogue to digital converter is said to achieve an 'industry best' snr of 82dBFS and spurious free dynamic range (sfdr) performance of 90dBc with a 30MHz input. The device has been designed for high performance data acquisition systems in medical imaging, industrial, spectrum analysis, multimode radio and radar applications. "In the medical imaging arena, our customers are constantly striving for higher resolution image capture that improves patient diagnostics," said Patrick O'Doherty, ADI's vice president for the Healthcare Group. "The AD9650 helps our customers achieve that goal by allowing medical equipment designers to increase imaging channel densities while still maintaining system-critical low noise and power requirements." Available in a 9x9mm package, ADI says the device provides flexibility for engineers using proprietary differential inputs at frequencies up to 300MHz and includes an on chip dither option for improved SFDR performance with low signal level analogue inputs.
