Working Principles

The AD669SQ is an analog-to-digital converter (ADC) that converts continuous analog signals into discrete digital values. It utilizes a successive approximation register (SAR) architecture to achieve high-resolution conversion. The input analog voltage is sampled and quantized into 16-bit digital data using an internal reference voltage. The converted digital data can then be processed by a microcontroller or other digital devices.
