Part Number: NE5532

Hi Team,

We would like to decrease the equivalent input noise voltage of NE5532.

Generally, if JFET is set to the input of bipolar amp, this amp can decrease equivalent input noise voltage.

Could you please let us know if you have the related TI application note?

Regards,

I believe you are talking about adding a very low noise gain stage before the NE5532. Would this be a separate stage or would the feedback from the NE5532 connect directly to the added input circuit?

What is the supply voltage, circuit gain and bandwidth for the application?

Hi Ron-san,

Thank you for your response.

Our specification is TBD so I will contact you if there is any progress.
