The ADS5562/ADS5560 family of 16-bit, single-channel, 40 and 80Msample/s ADCs (analogue-to-digital converters) provide high-level SNRs (signal-to-noise ratios) with very low power consumption (less than 900mW). The devices' low noise floor improves image quality in medical applications. The converters offer dynamic power scaling, reducing power consumption to as little as 540mW at 25Msamples/s. To further reduce noise, they 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. In addition, programmable gain from 0 to 6dB allows full-scale outputs to be provided for input signals as low as 2Vp-p. To further add to the devices' flexibility, designers can choose between parallel CMOS or fully differential double-data-rate LVDS outputs.
