Other Parts Discussed in Thread: LM4890,
Hi there!
In my product I have a single 0.8W / 8ohms speaker from CUI and an analog electret condenser microphone.
My interface to the remote CPU board is USB.
I was planning on using the USB Audio Codec PCM2912A and amplify the right channel audio signal with a LM4890 to drive my speaker. (Mono Audio)
Can you give me recommendations regarding the connection of the Codec and Amplifier? (To match impedances etc)
How do I connect them properly to get the best sound experience?
(EVM schematic and application is only for headphones and not for a speaker)
Thank you in advance!
