Overview
The ADC12D1800CIUT is a 12-bit, ultra-high-speed analog-to-digital converter (ADC) produced by Texas Instruments. It is part of TI's Ultra-High-Speed ADC family and builds upon the features, architecture, and functionality of the 10-bit GHz family of ADCs. This converter is capable of operating at either 3.6 GSPS in interleaved mode or 1.8 GSPS in dual ADC mode, making it highly versatile for various high-speed applications. The ADC is packaged in a 292-ball thermally enhanced BGA package and operates over an industrial temperature range of –40°C to +85°C.
