It is packaged in subminiature package to allow for easy integration with a magnetic core to create a highly accurate current sensing module. The programmable nature of the CHA611 enables it to account for manufacturing tolerances in the final current sensing module assembly. These ratiometric Hall effect sensor ICs provide a voltage output that is proportional to the applied magnetic field. The quiescent voltage output is user adjustable around 50% of the supply voltage and the output sensitivity...
