High-Precision 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 simply to monitor current levels for safety reasons. Our current sense amplifiers provide a high-flexibility, high-precision solution to maximize efficiency and reliability with a zero-drift architecture, which makes your design more robust across a wide range of environmental conditions and applications.

  • High-voltage current sense amplifiers featuring a wide specified input common-mode range provide the flexibility to address a variety of voltage rails, including overhead for transients
  • The zero-drift current sense amplifier architecture enables ultra-low offsets, allowing you to use smaller shunt resistors without sacrificing resolution
  • Integrated, on-chip Electromagnetic Interference (EMI) filters reduce high-frequency interference and are ideal for harsh, electrically noisy environments
