It's wrong too. You can't get more than 16V from that transformer without using a boost circuit.The power supply I got online is just fixed.
I want to use 5-15vdc for signal generator, current 200mA. Power dissipation?... I am using LM324It's wrong too. You can't get more than 16V from that transformer without using a boost circuit.
- What secondary voltage are you planning to use?
- What current do you want?
- Do you care about power dissipation in the regulators?
Give me a link of online store or if you have function signal generator schematic, post it to me, better than trying out things that will never workChange of subject to sine wave oscillators?
is this meant to be variable frequency? If so, the time constants of the second and third op-amps will have to be adjusted at the same time.
And why the second op-amp to make the triangle wave. There’s already a triangle-ish waveform in pin 2 of the first op-amp.
if you want a sine wave from an op-amp what’s wrong with a Wien bridge? You need far less gain bandwidth product or slewrate than you do to make the intermediate squarewave. If you want to start from a squarewave generate it with a 555. Opamps will always have slewrate limitations when trying to output a square wave.
maximum frequency? There are some very fast opamps out there - how much do you want to pay?.
variable frequency is the best, at least with little distortion, medium power output. variable Voltage, is the current not depending on the voltage? About current I don't know but hope the a bit high the betterHow good does it need to be? Minimum/maximum frequency? Distortion? Output level? Output drive current?
