CN-0350 gain tuning

Hi there,

I have the CN-0350 connected to my piezoelectric sensor. The data output is between 0 and 4096, which matches 0 to 2.5 V, as the datasheet explains. The offset is around 1.25 V. The attached picture shows the graph of my data when I press the piezoelectric sensor 4 times, while increasing the pressing force as we go from left to right. It is clear that the peak-to-peak amplitude of the signal is greater than 2.5 V. Can I tune the gain of the amplifier inside the CN-0350 so my signal will not hit the limits of the ADC converter (0 - 2.4 V)? if so, how can I do that?

Best,

Ebrahim
