TI ADS4128IRGZT

The ADS4128 is a 12-bit analog-to-digital converter (ADC) with a sampling rate of up to 200 MSPS. When powered by a 1.8V supply, this device uses innovative design techniques to achieve high dynamic performance while maintaining extremely low power consumption. This device is well-suited for multi-carrier, high-bandwidth communication applications. The ADS4128 features fine gain options, which 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, which can be used to eliminate ADC offset. At lower sampling rates, the operating power consumption of the ADC will automatically decrease without any loss of performance. The ADS4128 comes in a compact, ultra-thin quad flat no-lead (VQFN)-48 package and is rated for the industrial temperature range of -40°C to 85°C.
