Product Number: AD8146

In AD8146, if i leave my VOCMC pin as floating, my Common-mode voltage is fixed as +2.5V. And in Pg.No: 15, it is described as resistive divider with an impedance of approximately 12.5 kΩ set this level means a resistive divider of R1=R2=12.5K is pull up with +5V
sets this level. Now I need to set my common mode voltage to -0.6V. So,is it okay to pull up with 8.87K to -5V to generate -0.6V.

    Hello ,

    Based on simulations, I don't think that you will be able to bring the effect of the input offset to the output back to zero by applying a voltage on the Vocm pin. Please see the simulation…
