Dual 11-Bit, 200-MSPS ADC with SNRBoost: The ADS58C28 is designed for ADC sockets in high-density 2-transmit, 4-receive (2x4) and 4x4 wireless base station systems. The SNRBoost feature enables performance found in 12- and 14-bit ADCs by shaping the noise floor of the device in such a way that the in-band SNR is improved once digital filtering is applied to the converter's output.
