Analog Multiplexer (MUX): Input Voltage Range ±10V to ±15V

Component Specifications

Definition

An analog multiplexer is a solid-state electronic switching device used in industrial automation to sequentially connect multiple analog input signals (such as voltage or current from sensors) to a single analog-to-digital converter (ADC) or processing unit. It functions as a multi-position switch controlled by digital address lines, enabling efficient signal acquisition in data acquisition systems by reducing the number of required ADCs and simplifying wiring.

Working Principle

The analog multiplexer operates by using digital control signals to select one of several analog input channels. Internally, it contains an array of electronic switches (typically MOSFET or CMOS transistors) that connect the selected input to a common output line. When a specific binary address is applied to the control pins, the corresponding switch closes, allowing the analog signal from that channel to pass through while other channels remain isolated, preventing signal interference.

Materials

Semiconductor silicon substrate with CMOS or MOSFET technology, encapsulated in plastic (e.g., epoxy resin) or ceramic packages with gold or copper lead frames for electrical connections.

Frequently Asked Questions

What is the difference between an analog multiplexer and a digital multiplexer?

An analog multiplexer switches continuous analog signals (e.g., voltage, current) without digitizing them, while a digital multiplexer handles discrete digital signals (binary data). Analog MUX requires low on-resistance and high bandwidth to preserve signal integrity.

How does an analog multiplexer reduce system cost in industrial applications?

By allowing multiple analog sensors to share a single ADC and processing unit, it minimizes component count, reduces wiring complexity, and lowers overall system cost while maintaining signal acquisition capabilities.
