Current Sense Amplifiers

The need to accurately measure a dynamic current is critical in a wide variety of applications, such as monitoring or charging batteries, creating a current controlled feedback loop for a power supply or motor, or to simply monitor current levels for safety reasons. Microchip’s current sense amplifiers provide a high flexibility, high-precision solution to maximize efficiency and reliability with a zero-drift architecture which makes this solution more robust across a wide range of environmental conditions and applications.

Current Sense Amplifiers Highlights

  • A wide specified input common-mode range provides the flexibility to address a variety of voltage rails, including overhead for transients
  • The zero-drift architecture enables ultra-low offsets, allowing you to use smaller shunt resistors without sacrificing resolution
  • Integrated, on-chip electromagnetic (EMI) filters reduce high frequency interference, ideal for harsh, electrically noisy environments

Looking for a more integrated solution?

Microchip provides a variety of devices to monitor power, voltage, current, zero cross detection and energy accumulation. Whether you need to monitor a DC voltage or a single- or poly-phase AC line, our innovative and easy-to-use products provide highly integrated solutions to meet your design challenges.
