Current Sense Amplifiers

Analog Devices’ current sense amplifiers offer excellent performance for a wide array of automotive, motor control and power management applications. These devices accurately amplify small voltages in the presence of large common-mode voltages, and provide high bandwidth, as well as level shifting and bidirectional capability. Excellent dc and ac accuracy over a wide temperature range from –40°C to +125°C minimizes errors in your measurement loop while not sacrificing on cost and package size.
Difference amplifiers can also often be used in certain current sense applications, especially for applications with >100V common mode. Difference Amplifier Product Selection Table
