General Description

The ADS4249 is a member of the ADS42xx ultralowpower family of dual-channel, 12-bit and 14-bit analog-to-digital converters (ADCs).

Innovative design techniques are used to achieve high dynamic performance and consume extremely low power with a 1.8-V supply.

This topology makes the ADS4249 well-suited for multi-carrier, wide-bandwidth communications applications.
