The MAX391ESE is a high-performance, quad single-pole single-throw (SPST) analog switch from Maxim Integrated. Designed for precision applications, this device offers a combination of low power consumption and high switching accuracy, making it ideal for a wide range of uses in both digital and analog signal routing.

This analog switch operates from a single +5V to +30V supply or from dual supplies of ±4.5V to ±20V, providing designers with flexibility in various power environments. The MAX391ESE is characterized by its low on-resistance (R_ON) of 100Ω max, which remains flat over the specified signal range (0.5Ω max) and temperature range (5Ω max). This ensures minimal signal distortion and preserves signal integrity, which is crucial for precision applications.

The MAX391ESE features fast switching speeds (t_ON = 175ns max, t_OFF = 145ns max), contributing to efficient performance in time-critical applications. Additionally, it boasts low charge injection (10pC max), low power consumption (35μW max), and high off-isolation (-75dB at 1MHz), which minimizes crosstalk and unintended signal paths, enhancing overall system performance.

The device is equipped with TTL/CMOS-compatible digital inputs, which simplifies integration with digital control circuitry. It also has break-before-make switching, which prevents momentary shorting when switching channels. The MAX391ESE is available in a 16-pin narrow SO package, which is suitable for applications where space is at a premium.

Common applications for the MAX391ESE include signal routing in communication systems, audio and video switching, ATE equipment, and precision data acquisition systems. Its robust design ensures reliable operation in industrial environments and systems requiring high precision and minimal signal degradation.

With Maxim Integrated's reputation for high-quality components, the MAX391ESE is a reliable choice for engineers looking to implement precise analog switching with low distortion and high-speed performance in their designs.
