Dallas—Texas Instruments says its 14-bit, 210-MSPS ADS5547 analog-to-digital converter for video, radar, and imaging applications, a pin-compatible addition to the company's ADS5546 family, is the industry's fastest. In addition, the company's new ADS5527 is suited to 12-bit, 210-MSPS applications.
Both tout a signal-to-noise ratio (SNR) of up to 73.3 dBFS and a spurious-free dynamic range (SFDR) of 85 dBc at 70 MHz (input) for higher range and resolution in radar and imaging, more accurate power amplifier characterization, and higher quality video.
Other benefits include low power dissipation (total 1.2 watts), programmable power scaling, internal sample and hold circuitry, selectable output timing and level control, and parallel CMOS and DDR LVDS output options. Users also have an option to apply an external reference. The ADCs are suited for use with the company's THS4509 and THS9001 high-speed amplifiers, GC5016/8 wideband digital down-converter/up-converters, and CDCM7005 clock synchronizer and jitter cleaner.
