Overview
The ADC12J2700NKE10, produced by Texas Instruments, is a high-performance giga-sample analog-to-digital converter (ADC) designed for wideband sampling and digital tuning applications. This device leverages Texas Instruments' advanced ADC technology to sample a large block of frequency spectrum directly 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 device operates over an industrial temperature range of –40°C to 85°C and is packaged in a 68-pin VQFN package.
