Overview
The AD9266BCPZRL7-65, produced by Analog Devices Inc., is a high-performance, monolithic, single-channel 16-bit analog-to-digital converter (ADC). It operates from a single 1.8 V analog power supply and features a separate digital output driver supply that can accommodate 1.8 V to 3.3 V logic families. This ADC is designed for low power consumption and ease of use, making it suitable for a variety of applications requiring high-speed and high-accuracy data conversion.
