Interface - Analog Switches, Multiplexers, Demultiplexers

The MAX4610EPD is a single-supply, quad, audio and video, low-voltage multiplexer/demultiplexer (MUX/DEMUX) with integrated 1.8V to 5V level shifters, designed to switch audio and video signals. The MAX4610EPD’s low on-resistance and low power consumption make it an ideal choice for applications such as the routing of video, audio, and baseband signals, instrumentation switching and control, and data conversion. It is available in a 5mm×5mm, 24-lead TQFN package.

Application Field

The MAX4610EPD is designed for applications in the industrial, medical, instrumentation, and consumer electronics markets. Its significant features – low on-resistance, low power consumption, and wide supply voltage fields – make it an ideal solution for a variety of applications. In audio and video systems, it can be used for signal routing, noise reduction, and audio/video signal isolation. In instrumentation, it can be employed for switching control signals and data conversions. In industrial applications, it can be used as a fault-isolation switch or a signal isolation switch.

Working Principle

The MAX4610EPD consists of four independent analog switches controlled by four digital control inputs. The switches are configured in four separate channels, each with its own digital control input. Each channel consists of two switches connected in a four-to-one multiplexer configuration. The switches are designed to switch signals up to ±15V, with a maximum current rating of 50mA for each switch. The MAX4610EPD also features integrated level shifters, allowing the digital control inputs to be operated from a wide supply voltage range, from 1.8V to 5V. These level shifters allow the same signal input to be switched in both directions, from high to low and from low to high.

The MAX4610EPD supports single-ended, unipolar, and differential signal types. When a signal is multiplexed, the analog switch is the primary element connecting the signal from one source to another. The switches have low on-resistance ensuring minimal signal distortion and retain their high switching performance even at very low signal frequencies.

The MAX4610EPD features an integrated level-shift and control logic circuitry that allows the digital control inputs to be set to logic levels both higher and lower than the voltage at which the switches are enabled. The MAX4610EPD’s low power consumption and wide supply voltage range of 1.8V to 5V makes it an ideal choice for battery-powered and portable applications. Additionally, the low power mode quiets the noise floor in video systems.

Conclusion

The MAX4610EPD is an ideal solution for a variety of audio, video, instrumentation, and industrial applications. Its low power consumption, low on-resistance, and wide supply voltage range make it an ideal choice for a wide range of applications. Its integrated level shifters are compatible with a wide range of supply voltages, from 1.8V to 5V, and can be set to logic levels both higher and lower than the voltage at which the switches are enabled. The MAX4610EPD’s low power consumption and wide supply voltage range make it a great choice for battery-powered and portable applications.
