These devices use innovative design techniques to achieve high dynamic performance, while consuming extremely low power at 1.8-V supply. The devices are wellsuited for multi-carrier, wide bandwidth communications applications. The ADS412x and ADS414x devices have fine gain options that can be used to improve SFDR performance at lower f...
