The AD6640 is a high performance, low power, 12-bit analog-to-digital converter that runs on a single 5 V supply and supports 65 MSPS sample rate. It is designed for use in multichannel, multimode receivers, cellular/PCS base stations, and other applications.
The AD6640 is a high‑speed, 12‑bit analog‑to‑digital converter designed for multichannel, multimode receivers. It operates from a single 5 V analog supply and a 3.3 V digital supply, delivering CMOS‑compatible outputs at up to 65 MSPS while maintaining an 80 dB spurious‑free dynamic range.
The document provides full electrical specifications, absolute maximum ratings, pin descriptions, functional block diagrams, and typical performance graphs. It also includes an application example showing how the ADC can be used in a wideband receiver with dither to improve sensitivity.
