I have a piezo driver that consists of a 555 timer supplying a signal to a high power opamp. The setup works well, the piezo vibrates. The problem is that the opamp and piezo require around 80Vpp. So my portable device is using 10 PP3 batteries. I would like to replace the PP3 batteries with 4 AAA batteries.
These are my input and output power requirements. They aren't fixed in stone.
For opamp supply I require +40V to -40V. Opamp max output +35V to -35V at 50mA (About 4W)
4 AAA batteries supply 6V and 2A at a push. I say at a push because my piezo will only have a life of 5 minutes so I'm happy to burn out the batteries.
Piezo power +/-40V at 30mA
How should I do this?
Thanks.
