ADC lowers energy use
17 August 2010
16bit dual ADC achieves lowest noise performance in its class.
Analog Devices, Inc. (ADI) has released a dual 16bit 105 MSPS (mega samples per second), low-power, low-noise, ADC (analogue-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 328mW per channel, which is half the power per channel of other data converters, while achieving an industry best SNR (signal-to-noise ratio) figure of 82dBFS and SFDR (spurious-free dynamic range) performance of 90dBc with a 30MHz 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.”
Available in a 9mm x 9mm package, the AD9650 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. The new ADC is pin-compatible with ADI’s previously released dual ADCs, including the AD9268 16bit 125 MSPS, AD9251 14bit 80 MSPS and AD9269 16bit 80 MSPS converters, allowing system engineers to raise the performance of their data acquisition systems without changing the board layout.
The AD9650 operates from a single 1.8V supply and a separate digital output driver supply, accommodating 1.8V CMOS or LVDS outputs. The AD9650 is also available in speed grade options of 80MSPS, 65MSPS and 25MSPS.
As part of a complete signal chain, it can be used with amplifiers, VGAs, and clock drivers such as the ADL5562 3.3 GHz ultralow -distortion RF/IF differential amplifier, ADA4937-2 ultralow -distortion differential ADC driver, AD8372 programmable dual VGA, AD9510 clock distribution IC and AD9520 CMOS output clock generator with integrated VCO.
