MAX4781EUE+T is a device that belongs to the category of interface-analog switches, multiplexers, demultiplexers. This device from Maxim Integrated is a low-on resistance dual SPST analog switch and multiplexer, built with CMOS technology for ease of use and versatility. This dual SPST switch can be separately used as a switch or a multiplexer.

The primary function of MAX4781EUE+T is to robustly handle signals in the range of -0.3V to VCC, as well as to improve system performance and reduce power consumption. Moreover, this device operates from a single 3V supply and can tolerate up to 1.1V of negative common-mode voltage. Regardless of its simplistic 4-pin configuration, the MAX4781EUE+T provides exceptional signal-handling capability and a wide range of features.

Application Field

The MAX4781EUE+T dual SPST analog switch and multiplexer, is perfect for a wide range of applications that require the transfer, selection, or movement of analog signals. This device can be used in various applications such as multiplexing, signal routing, conversion of signals, data acquisition, audio and video equipment, and medical equipment.

The MAX4781EUE+T is also suitable for use in any application requiring switching between two independent analog sources. This makes it an ideal choice for applications in communications and industrial control. Its low on-resistance makes it especially suitable for high-frequency applications, such as sampling oscilloscopes and high-end audio equipment.

Working Principle

The MAX4781EUE+T is a low-on-resistance dual-SPST CMOS analog switch and multiplexer with two pins for control and two pins for signals. It operates from a single 3V supply and can tolerate up to 1.1V of negative common-mode voltage. The MAX4781EUE+T is available in 8-pin SOIC and 8-pin TDFN packages.

The MAX4781EUE+T includes separate data inputs, data outputs, and a single logic control pin. Its high switching speed makes it ideal for applications that require fast switching. With its 0.3Ω max on-resistance, it can be used in high-fidelity audio equipment. It has built-in low-on-resistance modulation diodes, which eliminate the need for external pull-down or pull-up resistors.

The MAX4781EUE+T can be used as an analog switch, to route signals between two separate data inputs. It can also be used as a multiplexer, to take one of two data inputs and route it to a single data output. The control logic pin determines whether the switch should be on or off. It can be used in both latching (switch latching) and non-latching (switch transient) modes.

The MAX4781EUE+T is highly robust with its wide common mode range and high CMOS threshold. It provides good thermal stability, low cross-talk, and low crosstalk, making it suitable for sensitive applications. The device features operator-controlled power-down functions, which enable it to place the device in a low-power state in order to reduce power consumption, while still providing full signal integrity.

Overall, the MAX4781EUE+T is highly advantageous for many applications involving the transfer, selection, or movement of analog signals. Its ability to robustly handle signals, low on resistance, and versatile features make it an ideal choice for many different applications. Since this device is designed to operate from a single 3V supply and can tolerate up to 1.1V of negative common-mode voltage, it is an optimal solution for many situations.
