Overview
The ADC12J2700NKET is a high-performance, 12-bit, 2.7 GSPS RF sampling analog-to-digital converter (ADC) produced by Texas Instruments. This device is designed for wideband sampling and digital tuning, enabling the direct sampling of a large block of frequency spectrum at RF frequencies. It features an integrated Digital Down Converter (DDC) that provides digital filtering and down-conversion, making the selected frequency block available on a JESD204B serial interface. The ADC12J2700NKET operates over an industrial temperature range of –40°C to 85°C and is packaged in a 68-pin VQFN package.
