Overview
The ADC12D800RFIUT/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 applications requiring high bandwidth and excellent noise and linearity performance at RF frequencies. The ADC12D800RF extends the usable range beyond the 7th Nyquist zone, enhancing the performance of TI’s GSPS ADCs. It 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.
