Overview
The AD9609BCPZ-65, produced by Analog Devices Inc., is a high-performance, monolithic, single-channel 10-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, ease of use, and excellent performance, making it suitable for a wide range of applications.
