MAX4073FAXK-T Current-Sense Amplifier from Maxim Integrated

The MAX4073FAXK-T is a high-quality current-sense amplifier designed by Maxim Integrated, a company renowned for its innovative and reliable integrated circuits. This particular component is engineered to accurately monitor the current through a shunt resistor in a wide array of applications, including but not limited to power management, battery charging, and automotive systems.

The MAX4073FAXK-T features a high-side current-sense amplifier, which means it is capable of measuring the current flowing through a shunt resistor placed between the positive supply rail and the load. This positioning allows for the detection of current without interfering with the ground plane, thus ensuring system stability and reducing noise interference.

One of the standout attributes of the MAX4073FAXK-T is its wide input common-mode voltage range, which extends from 3V to 28V, making it suitable for a variety of power systems. Furthermore, the device offers a precision current-sensing solution with a low input offset voltage, which translates into accurate current measurement even at low current levels.

The MAX4073FAXK-T is also characterized by its high accuracy and low power consumption. It has a quiescent current of only 21µA, which is ideal for battery-powered and energy-sensitive applications. Additionally, the device is equipped with a gain of 20V/V, providing a significant amplification of the voltage across the shunt resistor, thereby facilitating easy and precise readout by an analog-to-digital converter (ADC) or microcontroller.

Packaged in a small 5-pin SC70 package, the MAX4073FAXK-T is designed for space-constrained applications. Its compact form factor does not compromise on performance, making it an excellent choice for designers looking to save board space without sacrificing functionality.

In summary, the MAX4073FAXK-T from Maxim Integrated is a versatile, high-performance current-sense amplifier that offers a compact solution for precise current monitoring across a broad range of applications. With its high accuracy, low power consumption, and wide input voltage range, it stands out as a top choice for engineers and designers in need of a reliable current-sensing component.
