25 kHz signal amplifier using op-amp
So I have this schematic to drive a transducer load from op-amp at 25 kHz (ultrasonic sound). The problem is, all I do is simulating it using LTSpice but I can't find the final result even though my ...

What's the actual specs on the TCT40-16T/R Ultrasonic Transducer?
I can't seem to find a definite datasheet about it. The closest thing I found was this. It says the max driving voltage is 80V but some of the other stuff I found said it's suppose to be 20Vrms (...
