Hi,
Do you agree the FAN4174 CMOS input opamp doesnt need R4 and R5 to both be 1MEG?
R5 is 1MEG to make the gain of the integrator low.
But R4 doesnt need to also be 1MEG. Would you agree.?

FAN4174 opamp

Page 5 shows the input bias current is a mere 5pA.....so no need to "balance" the input resistors
