Texas Instruments  ADS4128IRGZT

The ADS4128 is a 12-bit analog-to-digital converter (ADC) with sampling rates up to 200 MSPS. This device uses innovative design techniques to achieve high dynamic performance, while consuming extremely low power at 1.8-V supply. The device is well-suited for multi-carrier, wide-bandwidth communications applications.

The ADS4128 has fine-gain options that can be used to improve SFDR performance at lower full-scale input ranges, especially at high input frequencies. It includes 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 ADS4128 is available in a compact VQFN-48 package and is specified over the industrial temperature range (–40°C to 85°C).
