The MAX381EPE from Maxim Integrated is a precision, quad, single-pole single-throw (SPST) analog switch designed to provide high-performance switching capabilities for a wide array of applications. This device is particularly well-suited for systems requiring low distortion, low noise, and low power consumption.

Featuring four independently controllable switches, the MAX381EPE offers a versatile solution for signal routing. Each switch conducts equally well in both directions when on and has an input signal range that extends to the power supplies. In the off state, signal levels up to the supplies are blocked. This feature makes the MAX381EPE ideal for multiplexing and demultiplexing applications, as well as for use in sample-and-hold circuits and as a track-and-hold amplifier.

The MAX381EPE operates from a single +4.5V to +30V supply or from dual supplies of ±4.5V to ±20V. The device also boasts a low charge injection of less than 10pC, making it an excellent choice for precision data acquisition systems. Furthermore, with its low power requirements, typically drawing less than 5µA of supply current, it is well-suited for portable and battery-powered equipment.

The device's on-resistance is matched between switches to 5Ω max and is flat (0.5Ω max) over the specified signal range. These features ensure minimal signal distortion and make the MAX381EPE reliable for applications that require consistent performance, such as audio and video signal routing.

Packaged in a 16-pin plastic DIP, the MAX381EPE is designed for ease of implementation into existing systems. Its pin-compatible upgrades and various other versions offer flexibility for a range of design needs, ensuring that engineers can find the right fit for their specific requirements.

Maxim Integrated's commitment to quality and performance is evident in the MAX381EPE, making it a smart choice for designers looking for a robust analog switching solution.
