Working Principles

The AD766SD/883B operates on the principle of successive approximation. It samples the analog input voltage, compares it to a reference voltage, and iteratively adjusts the digital output until the difference between the two voltages is minimized. This process is repeated for each bit of the digital output, resulting in a high-resolution digital representation of the analog input.
