I am generating a sine wave using a micro-controller and resistive ladder,freq of 100Hz-800Khz. it is than shifted to 0v origin using level shifter circuit, and amplified to 5V peak to peak.
I need this 5Vpp signal to amplified to 70vpp-90Vpp, using a suitable voltage amplifier, do I use a single stage amplifier to do this or a 2 stage, like the first one amplifies to 30Vpp a filter stage in between and than a second stage to take it to 70vpp or 90vpp. What sort of amplifier should be used class A or Class AB.
dual supply voltage of +/-50V can be provided using a SMPS , the output voltage swing is needed more than the power [current]. the load is a 8Ohm coil.Any circuit or theory will help.
Please advise. Thank you.
