MAX4713EUE+ Application Field and Working Principle

Interface technology is becoming increasingly important to the advancement of modern systems in a wide array of application fields, ranging from consumer electronics to medical devices. The MAX4713EUE+ is a monolithic CMOS-based analog switch designed to address expectations for precision. As a member of the MAX4713 family of analog switches, multiplexer, and demultiplexer products, the MAX4713EUE+ has proven useful in an array of application fields due to its ability to provide excellent performance at low supply voltages. It is part of the Interface family of products that also includes analog switches, multiplexers and LEDs.

Application Fields

The MAX4713EUE+ is an 8-Channel Analog Multiplexer/Demultiplexer that provides much better performance than conventional mechanical switches in applications where the speed or accuracy of the switch is critical. Primary application fields include the selection of multiple audio signals, power ablation control (addressing the limit of N+1 electrodes), and traditional consumer electronic multiplexing. Other general applications include thermocouples, audio switching, and analog control/measurement circuits.

Performance Specifications

The MAX4713EUE+ boasts excellent performance-level specifications, including a break-before-make switching scheme, an on-resistance variation of less than ±3%, an off-leakage current of less than 1 nA, and a maximum on-resistance RON of 552 Ω. Additionally, the device has a data-dependent specification for RON of ±1.5% from channel to channel. The device can also be operated in a wide supply voltage range from 2.7V to 3.6V.

Working Principle

The MAX4713EUE+ is a bidirectional, monolithic CMOS switch that uses metal-oxide-semiconductor (MOS) technology. In the forward direction, each switch is connected to the output and the corresponding address selection line is driven to an appropriate voltage. The switches are driven by N (channel select) inputs to either a high or low logic level. When the logic level applied is high, all the channels are connected to the output pin, and when the logic level is low, each switch connects the appropriate channel to the output pin.

The off-state leakage current is limited by a series MOSFET. This ensures that the switch remains off with extremely low leakage current even when powered off. The MAX4713EUE+ supports two different power-on states, which can be set by the user. The open-drain capability allows the user to achieve an active high power-on state.

Conclusion

In conclusion, the MAX4713EUE+ is a member of the MAX4713 family of analog switch and multiplexer products that provide excellent performance at a low supply voltage. With its low-noise feature, it is tailored to meet the needs of a diverse range of applications from consumer electronics to medical devices. Its performance specifications and working principle make it a great choice for audio and general application multiplexing.
