Can anyone help, I am looking for a replacement for LM387 Low Noise Dual Preamplifier which is now discontinued, I have look on the net but no luck but maybe I am looking in the wrong place.



Thanks

Do you mean replacement as in a direct substitute ? No alternative I know of.

I do not mind if the pin out is not the same (DIL or SIL) but it must be low noise and bandwidth for 10 MHz or better, below is the spec.

I have tried a NJM4558 but it was not very good.

? Low noise: 1.0 µV total input noise ? High gain: 104 dB open loop ? Single supply operation ? Wide supply range LM387: 9 to 30V LM387A: 9 to 40V ? Power supply rejection: 110 dB ? Large output voltage swing (VCC - 2V)p-p ? Wide bandwidth 15 MHz unity gain ? Power bandwidth 75 kHz, 20 Vp-p ? Internally compensated ? Short circuit protected

Hi ! Tom,

We do have stock of the LM387 from NS. But the cost for several pcs is expensive.

Our delivery cost is US$10.00 ( 7 to 14 days ). I cannot sure we can help you or not.

Thanks !

No, it wouldn't be. Are you not familiar with audio devices ?

The LM387 is a true POS actually, you're better off without it !

Is this for a new design ? Details ?

If you can move the leads around, how about a NJM2068, or a TLC2272?
