In July 2011, Texas Instruments (TI) expanded its line of high speed, ultra low power consumption analogue-to-digital converters (ADCs) with eight dual channel devices available in 12- and 14-bit resolutions at speeds from 65 to 250 MSPS. With these additions, the ADS42xx family provides the performance and bandwidth needed for 3G/LTE wireless base stations, portable test and measurement, and software defined radio applications, while providing best-in-class power consumption.

Features and USP: The ADS42xx family provides the performance and bandwidth needed for 3G/LTE wireless base stations, portable test and measurement, and software defined radio applications. The 14-bit ADS4246 uses 332 mW total power at 160 MSPS. This family of converters provides options down to 92 mW per channel to reduce board heating and operating costs. The 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.
