RC4580: RC4580 : We Planing to use RC4580 for MIC Ampilfer

Hi Luis,

Do you see any issue to proceed with the same RC4580 Amplifier?

Thanks

Hi, Saumil,

The mic pre amplifiers that I recommended will result in a better performance since they have been designed for this kind of applications. If this is not an inconvenient, you can proceed with the RC4580.

Hi Luis,

I agree with you but there are two things-

1. RC4580 datasheet also suggests the below applications-

• Audio Preamplifiers
• Headphone Amplifiers 

2. RC4580 is a very low-cost solution compared to any other Op-amp solution.

We are using the RC4580 as Non-inverting amplifier

Can you please review the attached schematic and provide the comments on it?

Thanks

Hi, Saumil,

Thank you for sharing the details of your pre amplifier circuit. I think the solution is alright for a non inverting amplifier. I didn't find anything to modify or adjust.

I agree with you, the RC4580 is a low cost solution for your application. Please let me know if you have additional questions or comments on this.

Best regards,

Hi Luis,

Thank you for your suggestions.

Is schematic looks completely ok or do you have any inputs on that?

We are planning for the Production of 10,000 quantities.

Thanks

Hi, Saumil,

I reviewed the entire schematic and I didn't find anything to modify. The connections seem to be all in order.
