Dear All,


We are developing the product which used ADM489A.


The A/B input impedance is described to be 12kohm in the data sheet.

however, It seems that there is no information more than them about the A/B input.


Please let me know an equivalent circuit which is in the data sheet of other suppliers.

*An attached file is the product of Texas Instruments.


As for it, description by a text is also useful for me.


Best Regards,
