DA7212 maximum input voltage at AUX inputs

Hi,

What is the maximum and minimum voltages the DA7212 can accept at the AUX inputs without (the risk of) damaging the IC?
In our circuit VDD_A is 1,8V.

Hello

We cannot guarantee anything beyond the datasheet values. For an Aux differential signal: 1.6 * VDD_A.

Kind regards,

So, according to the

So, according to the datasheet Vmax at AUX input for single ended is 0.8 × VDD_A Vpp. Does it mean that Vmax_peak is +0,4 × VDD_A and Vmin_peak is -0.4 × VDD_A? I can't see that the datasheets says whether the signal should be symmetrical with respect to GND or VDD_A/2.

Hello,

Hello,

That correct, so VMAX is +0.4 x VDD_A and VMIN is -0.4 x VDD_B.

Does that make sense?

Kind regards,
Elliott

Yes, it does make sense and
