Data Converter uses 30 Percent Less Power
Mon, 12/14/2009 - 11:48am
Texas Instruments Inc. introduces the first in a new class of high-speed analog-to-digital converters (ADCs) delivering ultra-low power consumption and excellent dynamic performance across wide signal bandwidths from DC up to 550 MHz. At the maximum sample rate of 250 mega samples per second (MSPS), the 14-bit ADS4149 consumes 30 percent less power, while delivering 3-dB greater signal-to-noise ratio (SNR) than the nearest low-power ADC. This combination of power and performance enables greater efficiency and density while enhancing range and sensitivity in defense, test and measurement, and communications applications. The ADS4149 consumes as little as 275 mW per channel at 250 MSPS, while offering 72.5-dB SNR at 100-MHz input frequency. Dynamic power scaling reduces power consumption to 215 mW at 160 MSPS.
