14-bit ADC ADS4246 from TI uses 332 mW total power at 160 MSPS

Texas Instruments Incorporated has expanded its line of analog-to-digital converters ADS42xx family with eight dual-channel devices available in 12- and 14-bit resolutions at speeds from 65 to 250 MSPS targeting applications such as 3G/LTE wireless base stations, portable test and measurement and software defined radio. TI claims the 14-bit ADS4246 uses 332 mW total power at 160 MSPS, 35-percent less power than its closest competitor.

The other key features of ADS42xx family include:
The family provides options down to 92 mW per channel to reduce board heating and operating costs.
Pin-compatible with 11-bit, 200-MSPS ADS58C28
6-dB programmable gain option provides the flexibility needed to achieve a high signal-to-noise ratio of up to 73.6 decibel full scale (dBFS) and spurious free dynamic range (SFDR) of up to 91 dBc for high receive sensitivity in 3G/LTE wireless infrastructure.

Package: 64-pin QFN package.
