Project Description: the customer needs a piezoelectric drive chip to drive a piezoelectric motor with a load of 2uF, and needs to output a sine wave with a swing of 1kHz 30-90v.
The customer looked at the drv2665, drv2700 and drv8662, but when the load is 2uF, the output swing will be attenuated and can not reach 90V. Is there a good scheme recommended.
Or Can I build a high-voltage operational amplifier and boost for the circuit ，Is there a good proposal recommended？
I have an idea of the discrete solution with a high voltage Op-Amp and external boost converter ，Is there a high-voltage operational amplifier that meets the requirements？
