AD9640 is a 14-bit, 80/105/125/150 MSPS, 1.8 V dual analog-to-digital converter.
The AD9640 is a dual 14‑bit analog‑to‑digital converter supporting sample rates of 80, 105, 125 and 150 MSPS. It operates from a single 1.8 V supply with separate digital‑output supplies (1.8 V‑3.3 V), provides flexible analog input ranges, and includes fast over‑range detection, signal‑monitor and built‑in self‑test features. The device delivers low power consumption (as low as 2.5 mW in power‑down mode) and high analog bandwidth (650 MHz).
Designed for communications and software‑defined radio applications, the AD9640 includes detailed design‑guideline recommendations for power sequencing, PCB layout, and thermal management to ensure optimal performance.
