Current-Sense Amplifiers

Current-sense amplifiers (CSAs) monitor current flow through a shunt (sense) resistor and provide closed-loop feedback of system loads. Current-sense amps are optimized for a wide range of applications, including overcurrent protection and optimization of power monitoring systems. We offer a wide range of current-sense amplifiers for both high-side sensing and low-side sensing, as well as unidirectional or bidirectional current flow through the sense resistor.

Precision Current-Sense Amplifiers

Our broad portfolio of precision current-sense amplifiers help you measure multiple decades of current. Decrease your sense resistor impedance and improve system efficiency with our low offset current-sense amplifiers. Achieve faster signal processing and acquisition time for improved AC performance with our wideband current-sense amplifiers.

Precision CSAs

High Voltage Current-Sense Amplifiers

Our high-side, high voltage current-sense amplifiers offer input ranges up to +76V and down to -20V. These high voltage CSAs are ideal for applications such as motor control, electrical instrumentation, automatic test equipment (ATE), automotive electronic control units, communications base stations, network routers, and servers.
