Precision matching of on-chip resistors give the INA165x devices excellent CMRR performance. These resistors have matching that is far superior compared to external components, and are immune to mismatches introduced by printed circuit board (PCB) layout. Unlike other line receiver products, the INA165x CMRR is characterized over temperature and tested in ...
