Hi, Team
To measure VIO of integrated amp in DRV8702-Q1, VSP=VSN=0V. Then VSO should be VIO multiplied by Av. Is this correct?
The very name input offset voltage indicates that it has been referred to the op-amp input. This is done with all of the error sources because the actual output created by any error source depends on the closed loop gain (ACL) of the circuit, as seen from the error source. Thus VIO must be multiplied by ACL for the non-inverting circuit to be referenced to the output.
I would like to double confirm descriptions in datasheet:
In Equation 1, should VIO be multiplied by Av? Otherwise, VIO is assumed to be 50mV will violate the 10mV maximum.
And in Equation 2, should VIO also be multiplied by Av? And the description below: VSO should be VIO multiply Av.
