Analog Devices AD9641 14‑Bit 80/155 MSPS ADC Data Sheet
The AD9641 is a high‑speed 14‑bit ADC designed for communications and software‑defined radio applications. It offers a single‑ended 1.8 V supply, JESD204A high‑speed serial output, and built‑in self‑test capabilities. The device is available in a 32‑lead LFCSP package and operates over an industrial temperature range of –40 °C to +85 °C.
Key features include an on‑chip PLL for clock multiplication, configurable input ranges, low power operation (238 mW at 80 MSPS), and a flexible SPI‑compatible serial interface for configuration and control. The datasheet provides detailed electrical specifications, timing diagrams, and pin descriptions for designers.
