Overview
The ADC12D1600RFIUT from Texas Instruments is a 12-bit, RF-sampling analog-to-digital converter (ADC) capable of operating at high sampling rates. This device can directly sample input frequencies up to and above 2.7 GHz, making it suitable for applications requiring high bandwidth and excellent noise and linearity performance at RF frequencies. 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.
