Current Sense Amplifiers
Analog Devices’ current sense amplifiers offer excellent performance for a wide array of automotive and power management applications. These devices accurately amplify small voltages in the presence of large common-mode voltage, 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.
