16-bit dual ADC
1 September 2010
Analogue, Mixed Signal, LSI
Analog Devices has developed a dual 16-bit 105 MSps ADC (analog-to-digital converter) for high-performance data acquisition systems in medical imaging, industrial, spectrum analysis, multimode radio and radar applications. The AD9650 consumes 328 mW per channel while achieving SNR (signal-to-noise ratio) of 82 dBFS and SFDR (spurious-free dynamic range) performance of 90 dBc with a 30 MHz input.
Available in a 9 x 9 mm package, the device 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 AD’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.
