Maxim Integrated MAX4173ESA+T Current-Sense Amplifier

The MAX4173ESA+T is a high-performance, low-cost, current-sense amplifier from Maxim Integrated, designed for precision current measurement applications. This device is particularly well-suited for applications that require accurate monitoring of current flow through a shunt resistor, making it an ideal choice for power management systems, battery chargers, and overcurrent protection circuits.

Featuring a wide input common-mode voltage range from -5V to +28V, the MAX4173ESA+T is versatile and can operate in a variety of circuit configurations. This range allows the device to handle systems with varying ground potentials and to measure current in both high-side and low-side applications. The amplifier's high accuracy and low offset voltage ensure precise current measurement, which is critical for maintaining system efficiency and safety.

The MAX4173ESA+T comes in a small 8-pin SOIC package, making it suitable for space-constrained applications. Despite its compact size, it offers a robust feature set, including a fast 400kHz bandwidth that enables quick response to changes in load current. Additionally, the device boasts a low supply current of just 100µA, which contributes to energy savings in battery-powered devices.

With a gain of 20V/V, the MAX4173ESA+T provides a scaled voltage output that is directly proportional to the current passing through the shunt resistor. This allows for easy interfacing with analog-to-digital converters (ADCs) or microcontrollers for further signal processing and analysis. The device also includes integrated precision resistors which simplify the design process by reducing the number of external components required.

The MAX4173ESA+T is available in tape and reel packaging, denoted by the "+T" suffix, making it suitable for automated assembly processes and high-volume production. Its robust design and comprehensive features make it an excellent choice for designers looking for a reliable and cost-effective solution for current sensing in industrial, automotive, and consumer applications.

With Maxim Integrated's commitment to quality, the MAX4173ESA+T is a reliable component that will enhance the performance and efficiency of a wide array of electronic systems.
