So basically I'm trying to make a circuit for a piezo-electric actuator. I only have access to a single supply at +70V for my op amp, an OPA445AP. Vin varies between 0 and +3V. I've looked at the help given by TI in this PDF and have come up with the following circuit. I've implemented it but when I power it up, Vout saturates at around +68V regardless of Vin. When I've simulated the circuit it indicates that it should work as expected.
Have I messed something with my circuit design up or is the OPA445AP not suitable for use with a single supply? Thanks in advance for your help.
