Part Number: LMV321

Hi Team,

My customer is seeking for a amp.

1. For lineout signal amp

2. output 2Vrms

3. Can the part provide SNR?(signal to noise)

Honestly, I'm not familiar with the application. If you have better part that I can promote, please let me know. Thank you.

Regards,

Roy

Hi Roy,

2Vrms means 5.66V peak to peak? This is not possible with the maximum allowed supply voltage of 5.5V. Also keep in mind that the output of LMV321 cannot go all the way to the supply rails.

And the SNR can be calculated from the datasheet specifications referring to the input noise voltage density and input noise current density.
