Maxim Integrated MAX381ESE+ Precision Analog Switch

The MAX381ESE+ from Maxim Integrated is a state-of-the-art precision analog switch that offers high performance in a small package. This component is designed to facilitate the routing of analog signals in a variety of applications, including data acquisition systems, communication devices, and audio/visual equipment.

Constructed with Maxim's proprietary process technology, the MAX381ESE+ features low on-resistance (R<sub>ON) of just 100 ohms max, ensuring minimal signal distortion and power loss. This low on-resistance is matched with an R<sub>ON flatness of 4 ohms max, which is critical for maintaining signal integrity, especially in applications where multiple switches are used in parallel or series.

One of the standout features of the MAX381ESE+ is its excellent switching characteristics. With a fast transition time (t<sub>TRANS) of just 250ns max, this switch is capable of handling high-speed signals without introducing significant delays. Additionally, the device exhibits a low charge injection of 10pC max, which minimizes transient disturbances in the signal path upon switching — a crucial attribute for precision applications.

The MAX381ESE+ operates from a single supply voltage ranging from +4.5V to +30V or from dual supplies of ±4.5V to ±20V, providing designers with flexibility in various circuit configurations. Moreover, the device boasts a low leakage current (I<sub>LEAK) of only 2.5nA max at +25°C, which is essential for preserving the accuracy of high-impedance circuits.

For added convenience and reliability, the MAX381ESE+ includes fault protection against overvoltage up to ±40V, even when the power is off. This feature helps to prevent damage to the switch and the downstream components in the event of unexpected voltage spikes.

The MAX381ESE+ comes in a 16-pin narrow SO package, making it compact and suitable for space-constrained applications. With its robust feature set and Maxim Integrated's reputation for quality, this precision analog switch is an excellent choice for designers looking to enhance the performance and reliability of their electronic systems.
