I am working on a project in which a very high negative voltage is required. I have the following equipment
DC power supply with max output voltage of 300V
Function generator with a maximum peak-to-peak voltage output of 20 Vp-p
An electric probe, which is essentially a wire
I would need to control the electric potential of the probe using a sinusoidal waveform. For example, the waveform may have a frequency in the range of 30-50 Hz, a peak-to-peak voltage of about 150 Vp-p, and reach a DC offset of -300 V. It is important to reach voltages of about -350 V.
I was wondering if using a linear operational amplifier (op-amp) would be a doable way to create a waveform similar to the one described above.
Essentially, to use a function generator to create a signal (e.g., a sine wave of 30-50 Hz, DC offset of -20 V, peak-to-peak voltage of 20 Vp-p) and amplify the signal with an op-amp having a gain of 10. The output signal would have a same frequency, DC offset of -200 V, and peak-to-peak voltage of 200 Vp-p.
Is it possible to achieve those negative voltages with an op-amp? If yes, are there off-the-shelf op-amp able to do so?
EDIT The output current is 50 mA, at most.
