Data Converters Feature 6dB SNR

( 1 Jul 2008 )

Texas Instruments Inc.'s family of 16-bit, single channel, 40MSPS (ADS5560) and 80MSPS (ADS5562) analog-to-digital converters (ADCs) provide the highest signal-to-noise ratio (SNR) within the first Nyquist zone with very low power consumption. For instance, the ADS5562 offers 6dB greater SNR and 0.6 more effective bits than any other 80MSPS device consuming less than 0.9W of power. The device also offers dynamic power scaling, reducing power consumption to as little as 0.54W at 25MSPS. The devices' low noise floor improves accuracy in test and measurement, receiver sensitivity in wireless communications, and image quality in medical, industrial and military applications.

To further reduce noise, the devices offer a low-frequency noise suppression mode to eliminate the 1/f (flicker) noise, improving SNR by up to 4.2dB over a 1MHz band in baseband and time-domain applications.
