Overview
The ADC12J4000NKER is a high-performance, 12-bit analog-to-digital converter (ADC) produced by Texas Instruments. This device is designed for wideband sampling and digital tuning, making it suitable for various high-frequency applications. It features an integrated Digital Down Converter (DDC) that provides digital filtering and down-conversion, enabling the direct sampling of a large block of frequency spectrum at RF frequencies. The ADC operates over an industrial temperature range of -40°C to 85°C and is packaged in a 68-pin VQFN package.
