How to amplify a 25khz square wave that goes from -3.3v to +3.3v so that the amplitude is doubled
I have a 3.3v power supply (lithium ion battery) and am using a TI MPS430G2553 chip to generate a 25khz square wave using 2 PWM pins and a push-pull setup. This square wave goes from -3.3v to +3.3v. ...

What kind of Ultrasonic Transducer is capable of 85db at 25khz-40khz using 5vdc and is 1cm diameter?
I'm building a dog training device. I don't want to zap or shock the dog, but just produce an ultra-sonic sound that will discourage current behavior.
I tried an online schematic and it didn't get ...
