The MAX4374TEUB+T from Maxim Integrated is a high-accuracy, high-side current-sense amplifier that is designed to monitor battery or power-supply currents in portable and industrial applications. This precision amplifier is an ideal choice for systems that require current monitoring for battery life optimization, overcurrent protection, or load detection.

Key Features

• High-Side Sensing: The device measures the current drawn by a load by sensing the voltage drop across a shunt resistor placed in the high side of the circuit, allowing for ground-referenced loads and eliminating the need for a negative power supply.
• Wide Input Voltage Range: With an input common-mode voltage range from 0V to +28V, the MAX4374TEUB+T is versatile and can be used in a variety of systems with different supply voltages.
• Low Quiescent Current: The device has a low supply current of only 24µA, which is crucial for battery-powered applications where power efficiency is critical.
• High Accuracy: It offers a low input offset voltage, which translates to high accuracy in current measurements, ensuring precise monitoring and control of the system.
• Integrated Gain: The amplifier has a built-in gain of 20V/V, which simplifies the circuit design by eliminating the need for external gain-setting components.
• Small Package: The MAX4374TEUB+T comes in a tiny, space-saving µMAX-10 package, making it suitable for compact PCB layouts.
