Maxim Integrated MAX4721EUA+ Low-Voltage, Serially Controlled SPST Switches

The MAX4721EUA+ is a state-of-the-art, low-voltage, single-pole/single-throw (SPST) analog switch from Maxim Integrated, designed to deliver high performance with minimal power consumption. This compact and efficient switch is ideal for a variety of applications, including portable battery-powered devices, sample-and-hold circuits, and audio and video signal routing.

Constructed with Maxim's proprietary process technology, the MAX4721EUA+ operates with a single +1.8V to +5.5V supply, making it particularly suitable for low-voltage systems. The switch offers low on-resistance (Ron) of 100Ω (max) at +5V, which remains flat over the specified signal range (0.5Ω max on-resistance flatness). It also features low leakage current (

The MAX4721EUA+ comes in a space-saving 8-pin µMAX package, which is highly beneficial for applications where board space is at a premium. Moreover, the device's serial interface allows for the reduction of digital control lines needed, which further conserves PCB real estate and simplifies design.

For enhanced versatility, the MAX4721EUA+ includes an active-low shutdown feature that switches the device into a high-impedance state, thereby reducing power consumption to just 0.1µA (max) during standby. This makes the switch an excellent choice for power-sensitive applications.

The robust design of the MAX4721EUA+ ensures that it is tolerant to overvoltage conditions up to +6V, even when the device is powered off. This feature provides an added layer of protection for the integrated circuits in harsh electrical environments.

With its combination of low power operation, high-speed switching, and a small footprint, the Maxim Integrated MAX4721EUA+ is an optimal solution for designers looking to enhance the efficiency and performance of their systems without compromising on space or power.
