ADS58C48 - 30% lower Power than competing Quad ADCs

TI introduced the lowest power 11-bit, 200 MSPS ADC family, with quad (ADS58C48), dual (ADS58C28) and buffered single-input (ADS58B18) options. Featuring SNRBoost technology, the ADCs deliver enhanced in-band signal-to-noise ratio (SNR) for multi-carrier and multi-mode communications systems requiring up to 65 MHz of signal bandwidth, such as CDMA, WCDMA, TD-SCDMA, LTE and WiMAX.

For instance, the SNRBoost technology in the ADS58C48 provides up to 4.3 dB greater SNR at 185 MSPS across 60 MHz of bandwidth, delivering increased bandwidth and sensitivity for a wide array of communications applications including remote radio heads, software defined radios, wireless repeaters and MIMO and diversity receivers.
