I have been using the SparkFun Electret Microphone Breakout BOB-12758 from you for some time now.

Recently I have noticed they are not performing the same in our application as they have done previously.

In the past, boards have been fitted with the OPA344 opamp marked B44, as indicated on the product page.

On the latest batch we received, the opamp is marked EYU0. Please can you tell me what part this is and supply a datasheet if possible?

Thanks Russell, do you know if this is a permanent change to the IC used?
