ADS4149IRGZR 14 位 250MSPS 低功耗 ADC

ADS4149IRGZR 14 位 250MSPS 低功耗 ADC封装VQFN-48

The ADS414x/2x are a family of 14-bit/12-bit analog-to-digital converters (ADCs) with sampling rates up to 250MSPS. These devices use innovative design techniques to achieve high dynamic performance, while consuming extremely low power at 1.8V supply. The devices are well-suited for multi-carrier, wide bandwidth communications applications.

The ADS414x/2x 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 ADS414x/2x are available in a compact QFN-48 pacakge and are specified over the industrial temperature range (–40°C to +85°C).
