TDA2050 Amplifier Circuit
I don't know if this is correct section for this but here goes, a Radio Amateur I know recently started to construct a solid state amplifier using a TDA2050, but the book he got the circuit from I can not find the info, and this circuit included the pre-amp. Does any member know where I can find a complete circuit like this as I would love to have a go at making an amplifier that has few components and is of use. PM me if you have the answer please
Best wishes Ken |

Re: TDA2050 Amplifier Circuit
All the TDA20xx devices are basically just op-amps with enough oomph in the output stage to drive a loudspeaker. As with all op-amps, available gain decreases with frequency, but don't rely on this alone to keep the circuit stable. You will find application circuits in the data sheets.
For the pre-amp, you might find a suitable application circuit in the data sheet of a low-noise op-amp such as the NE5534 / 5532. You just need possibly an RIAA phono stage, an input selector switch (maybe even separate "listen" and "record" switches), and volume and tone controls.
