I have created a circuit for which I would like a rail to rail output of 0 - 15V, using an OPA548 with the driving waveform generated by a microcontroller DAC powered by 3.3V.
The datasheet for OPA548 is given here: OPA548 High-Voltage, High-Current Operational Amplifier
The selected gain is about 4.5 V/V, such that the output of the op-amp saturates when the input waveform is at 3.3V.
Using an oscilloscope, when providing a 0-3.3V sine wave on the 'DAC_OUT' pin, the 'PULSE_OUT' pin will always saturate to 0V or 15V (similar to a square wave), and never follows the curve of the sine wave. Originally, I believed that this was an input bias current issue on the op-amp input pin, for which I added a 2.2KOhm resistor in series between the 'DAC_OUT' signal and op-amp inverting input, however this did not fix the issue.
