DESCRIPTION

TMR7401 series leakage current sensor based on magnetic induction principle, incorporate

s our tunneling

magnetoresistive (TMR) sensor with high sensitivity and high SNR. With the build in conditioning circuits for

offset voltage, temperature and non linearity compensation , it provides accurate measurement of DC, AC and

pulse current. TMR7401 p rovides excellent primary to secondary g alvanic isolation, low power consumption

and compact size design.
