The ADS412x and ADS414x devices are lower-sampling speed variants in the ADS41xx familyof analog-to-digital converters (ADCs). These devices use innovative design techniques to achievehigh dynamic performance, while consuming extremely low power at 1.8-V supply. The devices arewell-suited for multi-carrier, wide bandwidth communications applications.

The ADS412x and ADS414x devices have fine gain options that can be used to improve SFDRperformance at lower full-scale input ranges, especially at high input frequencies. They include adc offset correction loop that can be used to cancel the ADC offset. At lower sampling rates, theADC 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 arespecified over the industrial temperature range (–40°C to +85°C).
