Maxim Integrated MAX4375FEUB High-Side Current-Sense Amplifier

The MAX4375FEUB from Maxim Integrated is a state-of-the-art high-side current-sense amplifier designed for precision current measurement in a compact µMAX-10 package. This device is ideal for a wide range of applications, including but not limited to, power management, battery charging, and overcurrent protection circuits.

With its high-side current sensing capability, the MAX4375FEUB can measure the current flowing through a shunt resistor placed in the high side of the circuit, which allows for the detection of ground faults and provides a safer operation environment since the ground path remains uninterrupted. This approach also simplifies the circuit design by eliminating the need for a differential amplifier to measure the voltage across the shunt.

The MAX4375FEUB boasts a wide input common-mode voltage range from 0 to 28V, making it suitable for many different supply voltages. It is also capable of operating from a single 2.7V to 5.5V power supply, which adds to its versatility in various system designs. The device offers a fixed gain of 20V/V, providing a precise amplified output that is proportional to the current through the shunt resistor.

Furthermore, the MAX4375FEUB features a low input offset voltage, which ensures accurate current measurement with minimal error. This high accuracy, combined with a fast 500kHz bandwidth, makes it an excellent choice for dynamic load monitoring and control. The device also comes with an integrated filter to reduce the noise and improve the signal-to-noise ratio, which is essential for precise measurements.

The MAX4375FEUB is designed with the end-user in mind, offering a robust construction that can withstand electrostatic discharge (ESD) events. This durability, along with its small footprint, makes it an excellent option for space-constrained applications. Whether you're designing a portable device, a power supply, or a sophisticated industrial system, the MAX4375FEUB high-side current-sense amplifier is a reliable and efficient solution for your current sensing needs.
