Working Principles

The AD669BNZ is an analog-to-digital converter (ADC) that converts continuous analog signals into discrete digital values. It utilizes a 12-bit resolution to provide accurate representation of the input signal. The ADC operates by sampling the analog input voltage at a high speed, converting it into a binary digital code.

The device uses a built-in reference voltage to establish the input voltage range. The sampled analog voltage is compared to this reference voltage, and the resulting digital code represents the magnitude of the input signal. The ADC also incorporates a successive approximation register (SAR) algorithm to determine the digital output.
