Maxim Integrated MAX4081TEUA High-Side Current-Sense Amplifier

The MAX4081TEUA from Maxim Integrated is a precision, high-side current-sense amplifier that is ideal for a wide range of applications, including portable PCs, cell phones, and other systems where battery/DC current monitoring is critical. Designed to operate over a wide supply voltage range from 2.7V to 76V, this versatile component is suitable for both low and high voltage systems.

One of the key features of the MAX4081TEUA is its ability to sense the current through an external sense resistor over a wide range of common-mode voltages. The high-side current sensing allows the detection of current in systems where the ground is not accessible, or its potential is variable, ensuring accurate current measurement under all conditions.

The device offers a fixed gain of 20V/V, which simplifies the design process by eliminating the need for external gain-setting components. This fixed gain also contributes to the MAX4081TEUA's high accuracy, making it a reliable choice for precision current monitoring tasks.

The MAX4081TEUA features a low input offset voltage, which enhances its performance in applications requiring precise current measurement. Additionally, the device boasts a fast response time, which is critical in systems that require quick reaction to overcurrent conditions or for real-time monitoring.

With its small 8-pin µMAX package, the MAX4081TEUA is not only space-efficient but also offers a reduced footprint on the PCB, making it an excellent choice for compact designs. The operating temperature range of -40°C to +125°C ensures reliable performance in both commercial and industrial environments.

Maxim Integrated's commitment to quality is evident in the MAX4081TEUA, as it provides robust performance for current sensing applications where space and power efficiency are at a premium. Whether it's for power management, overcurrent protection, or battery charging systems, the MAX4081TEUA is an ideal component for designers who require a high-performance, easy-to-use current-sense amplifier.
