Interface - Analog Switches, Multiplexers, Demultiplexers: MAX4802CXZ+ Application Field and Working Principle

The MAX4802CXZ+ is an ultra-low leakage, low on-resistance, precision analog switch that contains two independent SPDT switches. It offers ultra-low on-state resistance and extremely low leakage current which make it an ideal choice for many audio and video applications. Moreover, they have a very low voltage drop across their control terminals and operate from a wide range of input voltages.

Application Field

The MAX4802CXZ+ is ideal for use as analog switches, multiplexers, and demultiplexers in a wide range of applications such as audio and video switching, level shifting and level conversion. It provides high immunity to noise, excellent linearity, and low unit-to-unit leakage. Its quick switching time, low on-state resistance, and low voltage drop across the control terminal make the MAX4802CXZ+ suitable for high-speed, low-power audio and video switching. Besides, they are also popularly used in transceiver applications, communication systems and switching systems.

Working Principle

The MAX4802CXZ+ is a precision SPDT analog switch with two independent switches. Each switch is composed of a cross-point formed by the two control terminals and two poles that connect two signal terminals. The switch is normally open and will close when the voltage applied to the emitter terminal equals the voltage applied to the collector terminal. This changes the impedance between the two signal terminals, connecting them together and allowing a current to flow. The MAX4802CXZ+ can handle up to 10A peak and can be driven with either TTL or CMOS logic level signals.

Conclusion

The MAX4802CXZ+ is a high performance, dual SPDT analog switch. It offers extremely low on-state resistance, low leakage current, and wide input logic levels. Its quick switch time and low on-state resistance make it ideal for high-speed switching applications. Furthermore, its ability to handle up to 10A peak makes it suitable for many audio, video and transceiver applications as well as level shifting and level conversion.
