Signal
The signal chain refers to the complete processing path in an electronic system, spanning from signal acquisition, conditioning, conversion to output. It covers the entire transmission and processing of signals from the physical world to the digital domain (or vice versa). As the core architecture of modern electronic devices (such as communication systems, medical instruments, and industrial control), it ensures high-fidelity, low-noise signal processing and precise control. Common components include operational amplifiers, comparators, ADCs, DACs, etc.
An operational amplifier is a high-gain direct-coupled amplifier composed of multiple parts. It operates based on the principle of differential amplification and has the characteristics of high gain, high input impedance and low output impedance. It has parameters such as gain-bandwidth product and is applied in fields such as signal amplification, signal operation and signal filtering.

A comparator is an electronic circuit that can compare two input signals and output corresponding logic levels according to the comparison result. When it works, the output is determined by the voltage relationship between the non-inverting input terminal and the inverting input terminal. It has parameters such as offset voltage, response time and output level characteristics. It can be divided into general-purpose type, high-speed type and high-precision type, and is applied in fields such as power management, signal detection and processing, ADC and DAC circuits.

DAC, namely Digital-to-Analog Converter, can convert digital signals into analog signals. Its working principle is based on specific network structures. It has parameters such as resolution, conversion accuracy and conversion speed, and can be divided into parallel and serial types. It is applied in fields like audio, video, industrial control and instrument and meter.
Isolation Products are critical components designed to achieve electrical isolation between circuits. They prevent the transmission of hazardous voltages, ground loop noise, and surge interference, while enabling the secure and reliable transfer of signals and/or power. Serving as fundamental safeguards within high-reliability systems—such as industrial controls, medical equipment, and communication interfaces—these products ensure personnel safety, equipment integrity, and signal fidelity. Common types include digital isolators, isolated interfaces (e.g., RS-485/CAN), and isolated power modules.
