Texas Instruments ADS4249
The ADS4249 is a member of the ADS42xx ultralowpower family of dual-channel, 12-bit and 14-bit analog-to-digital converters (ADCs). This topology makes the ADS4249 well-suited for multi-carrier, wide-bandwidth communications applications. The ADS4249 has gain options that can be used to improve SFDR performance at lower full-scale input ranges.| Part No. | ADS4249 |

DESCRIPTION
Innovative design techniques are used to achieve high dynamic performance and consume extremely low power with a 1.8-V supply. This device also includes a dc offset correction loop that can be used to cancel the ADC offset. Both DDR LVDS and parallel CMOS digital output interfaces are available in a compact VQFN-64 PowerPAD™ package.
