We are converting a single ended DAC output into differential. The DAC output composes a DC signal(-10V - +10V) and sine waves running below 100kHz(below 100mVpp). The DAC has an OpAmp voltage follower at the end of it already.
The reason for conversion is because I want to export a larger range of the output. The range of the single ended signal is 20V, while a differential one with same power supply could provide 40V range.
The load which the output voltage will exert on is a capacitor, so with very large impedance. I guess in this case the balanced outputs for differential voltages are not necessary.
Can I simply use a voltage inverter at the output of the DAC? The reason is that I can find small footprint OpAamps with several OpAmps in one chip.
What are the considerations when designing a converter for this purpose? Such as OpAmp selections, feedback resistors and etc..
I saw some applications use differential OpAmps. What are the benefits of them comparing with using OpAmps?
