ADIMAX40010FAUT+T
Overview
The MAX40010FAUT+T is a high-side current-sense amplifier designed to monitor currents across a wide input common-mode range of 2.7V to 76V. It features a very low maximum input offset voltage of 12uV and a gain of 50V/V, making it suitable for precision power monitoring in high-voltage systems. The device includes internal EMI filters to ensure robust performance in electrically noisy environments.
Why Choose This Part
The primary advantage is the exceptional 12uV offset voltage which allows for the use of very small sense resistors, reducing power dissipation. It offers a tight 0.1% maximum gain error for high-accuracy measurements and maintains a low 350uA supply current. The integrated EMI filters simplify PCB design by reducing the need for external filtering components in sensitive analog paths.
Applications
Key Specifications
Getting Started
To evaluate this part, use the MAX40010EVKIT evaluation kit which provides a proven layout and allows for testing different shunt resistor configurations. Ensure that the input common-mode voltage stays within the 2.7V to 76V range and place a 0.1uF ceramic bypass capacitor close to the VDD pin. For high-accuracy results, use a 4-terminal Kelvin-sense resistor layout to minimize trace resistance errors.
