In summary, Allegro MicroSystems has developed a line of fully integrated Hall-effect current sensor ICs that provide highly accurate output voltage signals proportional to the applied current. Advanced IC and packaging techniques enable bandwidth improvements above 120 kHz as well as low noise amplifier designs that improve device accuracy throughout the entire operating temperature range. The proprietary packaging techniques also provide small form factor devices with galvanic isolation and Allegro factory programming for stable zero amp and full scale output over temperature. These advances allow design engineers to use Hall-effect based current sensor ICs in new applications where increased energy efficiency or new operating features are required.
