AD9649 is a 14-bit, 20/40/65/80 MSPS, 1.8 V analog-to-digital converter.
The AD9649 is a monolithic, single‑channel 14‑bit ADC that operates from a 1.8 V analog supply and supports a 1.8‑3.3 V digital output driver. It features a high‑performance sample‑and‑hold circuit, on‑chip voltage reference, and a standard SPI serial port for configuration and test pattern generation.
Designed for communications, radar/LIDAR, handheld instruments and portable medical imaging, the device includes detailed design‑guideline recommendations for power distribution, grounding, and PCB layout to achieve optimal performance.
