Working Principles

The AD977BRZRL is an analog-to-digital converter that operates by sampling and quantizing analog signals. It uses a high-speed internal clock to sample the input voltage at regular intervals. The sampled voltage is then compared to a reference voltage, and the resulting digital value is stored in the output register. The conversion process is repeated continuously, allowing for real-time conversion of analog signals into digital data.
