Analog Devices Inc. (ADI) announces a dual 16-bit 105 MSPS (mega samples per second), low-power, low-noise ADC (analog-to-digital converter) designed for high-performance data acquisition systems in medical imaging, industrial, spectrum analysis, multimode radio, and radar applications. The AD9650 ADC consumes 328-mW per channel, which is half the power per channel of competing data converters while achieving an industry best SNR (signal-to-noise ratio) figure of 82 dBFS and SFDR (spurious-free dynamic range) performance of 90 dBc with a 30 MHz input.
Available in a compact 9 x 9 mm package, the AD9650 provides flexibility for engineers using proprietary 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 ADI’s previously released dual ADCs, including the AD9268 16-bit 125 MSPS, AD9251 14-bit 80 MSPS, and the AD9269 16-bit 80 MSPS, allowing system engineers to raise the performance of their 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. It is also available in speed grade options of 80 MSPS, 65 MSPS, and 25 MSPS.
