how to scale Aout from 0-3.3V to 0-10V?

Hello to the forum! (I´m beginner in microcontrollers and from Germany, so sorry for bad english :-)

Application: My application is a active vibration damping and I want to run a PID Controller on LPC1768. The analoge input would be the acceleration and the analoge output is the signal to piezoactor amplifier.

Problem: The piezoactor amplifier needs an input from 0-10V. The Aout (p18) provides only 0-3.3V.

What I´ve found in the forum so far: https://developer.mbed.org/users/AjK/notebook/scaling-mbeds-aout/ https://developer.mbed.org/users/eqon/notebook/industrial-io-board-mbed/

Question: Has anyone experience in creating a 0-10V Aout or know how to do it?
