Overview
The ADC12D1800RFIUT/NOPB is a 12-bit, high-speed RF-sampling analog-to-digital converter (ADC) produced by Texas Instruments. This device is capable of directly sampling input frequencies up to and above 2.7 GHz, making it ideal for various high-frequency data acquisition applications. It features a flexible LVDS interface compatible with IEEE 1596.3-1996 and supports programmable common mode voltage. The ADC is packaged in a lead-free 292-ball thermally enhanced BGA package and operates over an industrial temperature range of –40°C to +85°C.
