MAX14724EWP+T, a part of Interface - Analog Switches, Multiplexers, Demultiplexers, is developed in the field of analog integrated circuit, which is widely used in CMOS and TTL logic-compatible applications. It is an independent, bidirectional, single-pole/single-throw, usually ternary, device with a low on-resistance, low OFF leakage current, andsupports audio, column drivers and video applications.

Application Field of MAX14724EWP+T

MAX14724EWP+T is very popular in a variety of applications. It is widely used in multiplexers, demultiplexers, UHF, VHF, and FM radio loop antenna, cellular phones, displays, noise suppressors and radar systems. Furthermore, MAX14724EWP+T also offers a better solution for several specific audio applications, such as field-effect transistor (FET) biasing, analog switches, data packets switch and resonator in audio synthesis applications.

Working Principle of MAX14724EWP+T

MAX14724EWP+T can switch analog signals from 0V to 4.5V with a low on-state resistance and OFF leakage current. In terms of switching, it uses a chopper technique for low on-state resistance and low OFF leakage current to minimize distortion in the signal. It can be used as either a switch or a multiplexer/demultiplexer to allow multiple signals to be connected or disconnected from a single port as needed. For example, when switching from one signal to another, MAX14724EWP+T connects the desired signal while disconnecting the undesired signal. The actuation voltage (VS) is used to turn the switch ON. When VS is applied to the switch terminals, the currents flowing through the device flow in the same direction. This causes the resistance between the switch terminals to be reduced and an internal voltage drop occurs. The voltage drop causes a switching arc to form, allowing the switch to be turned ON.

When the current through MAX14724EWP+T is disconnected, the resistance between the switch terminals increase and the voltage drop across the switch is minimized. This causes the switch to be turned OFF. The actuation voltage (VS) is also used to control the ON/OFF state of the switch. It can be used to control the ON state by applying a voltage to the switch terminals when the switch is OFF. This prevents unwanted ON current from flowing when the switch is not in use.

The OFF state of MAX14724EWP+T is also controlled by the actuation voltage (VS), though in this case it is used to isolate the switch\'s OFF state. This is done by applying a voltage to the switch terminals while the switch is OFF. This ensures that the maximum OFF state resistance between its terminals is maintained and prevents any parasitic ON currents from flowing.

Conclusion

MAX14724EWP+T is an independent, bidirectional, single-pole/single-throw switching device for interfacing analog signals with TTL and CMOS logic compatible devices. It is a popular part of the Interface - Analog Switches, Multiplexers, and Demultiplexers development. It has multiple application fields and its working principle is based on a chopper technique for low on-state resistance and low OFF leakage current. It turns ON when a voltage is applied to the switch terminals and turns OFF when the current should be disconnected. Besides, the actuation voltage (VS) is also used to control the ON/OFF state of the switch.
