Maxim Integrated MAX4080SAUA+T High-Side Current-Sense Amplifier

The MAX4080SAUA+T from Maxim Integrated is a precision, high-side current-sense amplifier designed for a wide range of applications requiring current monitoring. This device offers a unique combination of high accuracy, low power consumption, and ease of use, making it an ideal choice for power management systems, battery chargers, and overcurrent protection circuits.

One of the standout features of the MAX4080SAUA+T is its ability to operate over a wide supply voltage range, from 4.5V to 76V, without the need for external components. This flexibility allows it to be used in various systems without worrying about the compatibility of the supply voltage. Additionally, it boasts a high accuracy with a low input offset voltage, which ensures precise current measurement across its operating range.

The amplifier is capable of sensing small voltage drops across shunt resistors at the high-side of the load, which allows for the detection of current flow under high common-mode voltages. This high-side sensing is particularly useful in applications where ground disturbance cannot be tolerated.

Equipped with a gain of 20V/V, the MAX4080SAUA+T provides a large output swing with a small sense voltage, translating into lower power loss in the shunt resistor. The device also features a fast response time, making it suitable for detecting overcurrent conditions and providing quick protective actions.

The MAX4080SAUA+T comes in a small 8-pin µMAX package, which is ideal for space-constrained applications. It is also specified over the extended -40°C to +125°C temperature range, ensuring reliable performance in harsh environments.

With its robust design and high-performance characteristics, the MAX4080SAUA+T current-sense amplifier is a perfect choice for engineers looking to enhance the safety, efficiency, and reliability of their power management systems. Whether you're designing automotive electronics, industrial control systems, or portable devices, this amplifier will provide the critical current-sensing functionality you need.
