The ADS61B49 (ADS61B29) is a 14-bit (12-bit) A/D converter with a sampling rate up to 250 MSPS. It combines high dynamic performance and low power consumption in a compact 48-QFN package. An integrated analog buffer makes it well-suited for multi-carrier, wide bandwidth communications applications. The buffer maintains constant performance and input impedance across a wide frequency range.
The Texas Instruments ADS61B29 and ADS61B49 are high-performance analog-to-digital converters (A/D converters) featuring an integrated high-impedance analog input buffer. This design makes them well-suited for multicarrier, wide bandwidth communications applications, such as software-defined radio and wireless infrastructure. The devices offer a maximum sample rate of 250 MSPS and are available in a compact 48-QFN package.
