Maxim Integrated MAX9610FEXK+ High-Side Current-Sense Amplifier

The MAX9610FEXK+ is a precision, high-side current-sense amplifier designed by Maxim Integrated, a company known for its innovative and reliable analog and mixed-signal engineering solutions. This compact and efficient component is ideal for a variety of applications where accurate current monitoring is crucial, such as battery management, power management, and overcurrent protection systems.

With its wide input common-mode voltage range of 2.7V to 28V, the MAX9610FEXK+ can operate in a diverse range of environments, from low-voltage portable devices to higher voltage automotive and industrial systems. The device is capable of sensing currents from microamps to amps, which makes it versatile for different current sensing applications. The high-side measurement allows for the detection of current without interfering with the ground path of the monitored load, which is beneficial for maintaining system integrity.

Featuring a fixed gain of 25V/V, the MAX9610FEXK+ provides a precise amplification of the voltage across a sense resistor placed in the path of the current to be measured. This amplification enables the small voltage drop across the resistor to be converted into a larger, more easily measurable output voltage, which can be read by an analog-to-digital converter (ADC) or other monitoring circuitry.

The device boasts a low input offset voltage, which enhances the accuracy of current measurements, and a fast 500kHz bandwidth, which makes it suitable for high-speed applications. Additionally, the MAX9610FEXK+ offers a quiescent current of only 100µA, which helps to minimize power consumption in battery-powered devices.

The MAX9610FEXK+ comes in a small, 5-pin SC70 package, which allows for a minimal footprint on printed circuit boards, making it an excellent choice for space-constrained applications. The operating temperature range of -40°C to +125°C ensures reliable performance across a wide range of environmental conditions.

Whether you are designing a power supply, a portable device, or an industrial control system, the MAX9610FEXK+ from Maxim Integrated provides a robust and precise solution for your high-side current-sensing needs.
