Suggested Input Protection AD8253

Question asked by josiah47 on Aug 20, 2012

I am currently designing a breakout board for this amp and would like some suggestions on input protection.

My input is a piezo sensor(reverse speaker, home made, non powered) that puts out about 70mV full swing and no clue on the amps.

The data sheet says to use series resistors and low leakage diode clamps. I see the resistor examples but don't see any diode hook up examples.

 

My input voltage is -15,+15, any suggestion on where to start with resistor values and diode values, and placements.

 

Below is my current schematic, any tips or suggestions would be appreciated.

 

Thanks
