Home – IC Supply – Link.
Pins 1 and 5 are the offset null pins, which makes this a nonstandard application of the chip. Post as a guest Name. This is at the input stage of the preamp, so low noise would be a priority. Socketed too, which is right handy. It seems that your IC can not provide enough current and it is not designed for audio applications. You mean just by the input bias current? There are a lot of much lower distortion opamps that are designed for high end audio.
Since it’s still available, and cheap, I would go with the original. Your limitation is actually you need a single opamp, not a dual!!!! These operational amplifiers have internal unity-gain frequency compensation. Even if I crank up the power supply of LM to 20v – the speakers volume doesn’t increase. It is a very powerful IC, and easy to use and requires few components.

Been to Linear Tech to show how their ADC fails, two of the app circuit on switching regulator oscillate. ConradHJun 12, You must log in or sign up to reply here. ConradHJun 11, Very little amplification when amplifying audio signal with LM Ask Question.
Another problem is that the speakers output is as quiet as l318p output from headphones.

They feature a factor-of-ten increase in. The was a high performance chip in its dayBGW use them in their products extensively. I’ve got a phono preamp with a bad LM P.
You have to check the schematic to see if they’re using the offset pins daatasheet the inputs. Sign up or log in Sign up using Google. I suggest using LM it is a power dataaheet not only a voltage amplifier and it can provide gain up to The actual current gain is roughly the HFE of your transistors. Products conform to specifications per the terms of Texas Instruments standard warranty.
Why is the amplification factor so low, even through the datasheet states the the amplification factor is calculated based on: On all other products, production processing does not necessarily include testing of all parameters.
Disconnect the speaker and re-measure gain. But the problem is, it’s amplification level appears to be only a factor of 6x. Most audio opamps are 0. Products conform to dstasheet per the terms of Texas Instruments.
Your name or email address: I’m trying to build a very simple circuit, that will amplify an audio signal coming from a 3. Further, a single capacitor can be added to reduce the settling time for 0.
Moving the op-amp to the other channel moved the hum with it, and it still got hot. Do you already have an account?
Been challenging the app engineer more than a few times in those semi conductor companies. Thank you for you time.
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.
