Hi There,
I have 4x MA40S4R/S Ultrasonic Transducers, and a 12V Lead-Acid Battery. I need something to drive the ultrasonic transducers to about 40Khz at 20 Vpp TX. I have come up with using an astable 555-timer to create the 40Khz square-wave and I have tested it on the breadboard and on multisim and it works fine when I use one of the four transducers I have. The problem is I need to amplify the output so its output voltage is around 20Vpp so that way it works better. I have been messing with it in multisim but wondered if this was the best way to do it, or if you could help me by providing me recommendations to my circuit or if there is an even simpler approach to driving 4x transducers at 20Vpp 40Khz.

see attached pic of my multisim circuit, any help is greatly appreciated.
