The Goal :
To design a function generator -
Sine, Square
Constant output amplitude -
For sine wave : 10Vpp (Symmetric about origin)
For square wave : 5Vp to 0V swing
Variable Frequency (say 1k, 2k, 5k, 10k)
Short-listed ideas :
1. Wein Bridge Oscillator to generate sine wave and then diode + hex inverter to obtain square
2. XR 2206 (but output voltage is 2Vpp. Further amplification is needed). Also, MAX038 and ICL 8038 is out of production :/
3. Timer IC circuit (this I am not aware of how to proceed)
4. Mux capacitor/resistors to vary frequency
Questions :
1. Are there any other function generator ICs I can use?
2. I hear that Timer IC 555 can be used. Can anyone link me to a VERIFIED circuit diagram?
3. Also, in case of an Oscillator circuit, I believe Wein Bridge is best. Any alternatives?
Thanks. Kindly reply asap
