Hello,
I am new to the forum and looking for assistance.
I am trying to create an AC voltage source (sine or square wave) that provides a current of up to 200mA, between frequencies from 1Hz to 500Hz. So far I've been using a wave generator that can generate waves at the desired frequencies, but its maximal output voltage is 10Vpp, whose current in the circuit is 87mA. So, I need to amplify it, but I don't know how, because I looked for some amplification circuits, but they don't seem to work at low frequencies.
I think the ideal characteristics for this amplification circuit would be:
- Signal In - Vin: 0-8Vpp;
- Operating frequency : 1Hz to 300Hz, and if possible 500Hz;
- Signal Output - Vout: 0-20Vpp;
- Signal Output - Iout : 0-200mA;
Any suggestions, comments, circuit diagram, components that you may know or have, I appreciate it
