Analog switches are semiconductors that provide a switching function, allowing an electrical signal to pass or not pass between its two terminals. These semiconductor switches can be used in many applications, including test and measurement, communications, industrial, medical, and consumer electronics. The MAX4780ETE+ is a versatile family of analog switches that are designed to meet the needs of a wide range of applications.

The MAX4780ETE+ family offers a variety of solutions, including dual SPST analog switches, SPST low-noise switches, bidirectional switches, video switches, and multiplexers. The MAX4780ETE+ has three different device types with different sizes and features for different applications. The dual SPST switches are designed for general-purpose switching, such as directional control of signals, low-noise performance, or high-accuracy switching applications. The bidirectional switches are designed for bidirectional signal routing, low-power operation, or low-noise performance. The video switches are designed for high-resolution video applications. The multiplexers are ideal for routing signals from multiple sources in various configurations, or for switching multiple channels between two different paths.

Features

The MAX4780ETE+ family of analog switches offers several features that make it ideal for a wide range of applications. The devices are available in a small 10-pin TDFN package. This small size makes them well-suited for portable and space-constrained applications. The devices also feature low power consumption, with a maximum quiescent current of 2.5µA per channel. The digital logic supply voltage ranges from 1.65V to 5.5V, allowing them to be used in battery-powered applications. They have a wide signal range of -30V to +30V, with a nominal on resistance of 8Ω and low off-leakage current of 10nA. The devices also feature a fast activation and shutdown time of 45ns.

In addition, the MAX4780ETE+ family features ESD protection of up to 10kV, which makes them well-suited for automotive and medical applications. The devices also incorporate several safety features, such as a programmable on resistance mismatch tolerance of less than 3.5% and a minimum on resistance of 6Ω. The devices also have a programmable switch trip voltage of 0.1V to 4.9V. They are characterized for operation at temperatures from -40°C to +85°C, making them suitable for a wide range of applications.

Work Principle

The MAX4780ETE+ works by routing a signal from one circuit to another. When a logic control signal is applied to an appropriate control signal input (EN, SEL, or both depending on the device type) the signal is routed from the signal source to the selected signal path. This is equivalent to a signal being sent from one port to another when the switch is activated. The signal is routed in both directions, depending on the specific switch type.

The MAX4780ETE+ family of analog switches has a wide variety of applications, including test and measurement, communications, industrial, medical, and consumer electronics, as well as automotive and medical. The devices are also well-suited for use in portable, space-constrained, and battery-powered applications. The wide signal range, fast activation and shutdown time, low power consumption, and ESD protection makes them ideal for many different applications.
