Current sense amplifiers analog output

Enable improved system accuracy, feedback control and protection

parametric-filterView all products
Current sense amplifiers have unique front-end architectures that allow their inputs to see voltages that exceed supply. In addition, highly-matched, integrated resistors increase accuracy and stability over temperature while shrinking overall system size. Additionally, this accuracy allows for lower ohmic shunts and power dissipation. With our diverse portfolio of analog-output current sense amplifiers, you can meet your system's precision, drift, and voltage requirements.
