Max RPM with MAX9926 and 60-2 Triggerwheel? Outputvoltage VR-Sensor?

I soldered together this MAX9926 circuit.

Then I added a sine wave to it using the signal generator. From a signal voltage of around 70mVpp, the output produces a square wave signal. If I now increase the frequency, the output stops working at 90 Hz. If I increase the voltage to 1Vpp it goes up to 120Hz and then the signal is gone again.
It is clear to me that the signal voltage increases as the speed increases. But in what range is that from start to maximum RPM.
I would be interested to know what signal voltage such a VR sensor actually outputs.
Thanks to the resistors built into the board and the internal diodes, nothing should break even if I increase the voltage further, right?
