Description
AI
The ADS412x and ADS414x devices are lower-sampling speed variants in the ADS41xx family of analog-to-digital converters (ADCs). These devices use innovative design techniques to achieve high dynamic performance, while consuming extremely low power at 1.8-V supply. The devices are well-suited 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 full-scale input ranges, especially at high input frequencies. They include a dc offset correction loop that can be used to cancel the ADC offset. At lower sampling rates, the ADC automatically operates at scaled down power with no loss in performance.
The ADS412x and ADS414x devices are available in a compact VQFN-48 package and are specified over the industrial temperature range (–40°C to +85°C).
