LM is a typical BJT Op Amp with 33 Ohm output impedance and current limited to 20mA with internal Vbe drop but reducing gain from 1k to 1 also lowers output impedance but it is still current limited to about 0. For phono preamp, I’d try the LME LM is ln318p very old opamp, it is fast, but I don’t think you need this fast for audio.
On all other products, production processing does not necessarily include testing of all parameters. Do you already have an account?
Socketed too, which is right handy. However, unlike most internally compensated amplifiers, external frequency compensation may be added for optimum performance.
The LM is not designed to drive the speaker directly. Do I need to drive the speaker with a transistor to make it louder or what would be the proper method?
When I went to check for ripple again, I noticed the op-amp was hot after being on for maybe a datashedt. Home – IC Supply – Link. I’ve got a phono preamp with a bad LM P.
I’m hoping that with the power supply rebuilt it will stay good. Things I usually look for audio opamps are: This particular unit was made in I think, but its possible the design is even older. Sign up using Facebook. If the is used with a discrete front end, as they do in the old app notes, you can’t just put another opamp in there. Its a phono preamp from a radio station.

Been challenging the app engineer more than a few times in those semi conductor companies. It doesn’t even have a power switch.
Why is the white lead connected to the – input? I suggest using LM it is a power amplifier not only a voltage amplifier and it dayasheet provide gain up to Your limitation is actually you need a single opamp, not a dual!!!! I look for at least 20mA output daasheet. Why is the amplification factor so low, even through the datasheet states the the amplification factor is calculated based on: These operational amplifiers have internal unity-gain frequency compensation.
One opamp comes to mind is OPA single opamp: Home Questions Tags Users Unanswered.
