Dual 16-bit 105 MSPS ADC from ADI for data acquisition systems

Analog Devices has released the AD9650, a dual 16-bit 105 MSPS (mega samples per second), low-power, low-noise, ADC (analog-to-digital converter). It is designed for high-performance data acquisition systems in medical imaging, industrial, spectrum analysis, multimode radio and radar applications. This ADC consumes 328-mW per channel, which ADI claims is half the power per channel of competing data converters while achieving an SNR (signal-to-noise ratio) figure of 82 dBFS and SFDR (spurious-free dynamic range) performance of 90 dBc with a 30 MHz input.

"In the medical imaging arena, our customers are constantly striving for higher resolution image capture that improves patient diagnostics," said Patrick O'Doherty, vice president for the Healthcare Group, Analog Devices. "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."

The AD9650 provides flexibility for engineers using differential inputs at frequencies up to 300 MHz and includes an on-chip dither option for improved SFDR performance with low signal level analog inputs. The new ADC is pin-compatible with earlier models of ADCs from ADI such as the AD9268 16-bit 125 MSPS, AD9251 14-bit 80 MSPS and the AD9269 16-bit 80 MSPS thus enabling high performance in the data acquisition systems without changing the board layout.

The AD9650 operates from a single 1.8 V supply and a separate digital output driver supply, accommodating 1.8 V CMOS or LVDS outputs. The AD9650 is also available in speed grade options of 80 MSPS, 65 MSPS and 25 MSPS.
