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.
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.
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.
Our broad portfolio of nanoPower and Micropower current-sense amplifiers help maximize and extend system and battery life without compromising DC accuracy. These tiny CSAs are available in a variety of space-saving, small footprint packages, such as SC70, SOT23, and wafer level packages (WLP).
