Our family of fully integrated, high isolation current sensor solutions provides accurate measurement with very low resistance—all without the need for external isolation components.
I appreciate your kind comments and explanations. Here is my demands:
Signal: DC signal, Sampling rate: each 10mS, current step:200mA is enough, Interface: better to be an analog output voltage for ADC, SMD is more appropriate, less than 1*1 cm*cm, Price is not important
