Characteristics of Analog Differential Input

Differential input is a high-performance signal transmission method widely used in industrial measurement and precision data acquisition. Its core feature is eliminating common-mode interference by measuring voltage differences between two signal lines.

Characteristics of Single-Ended Input

The advantages of single-ended input are simplicity and low cost, making it suitable for short-distance, low-noise applications. Its disadvantages are poor noise immunity and reliance on a common ground. In complex environments, differential input or isolation solutions should be prioritized.

Why GPIO Cannot Be Isolated by Default

GPIO does not natively support isolation due to design and cost constraints, but external isolators can be added. Whether isolation is necessary depends on the application (safety, noise immunity, etc.).
