I want to drive a small mono-speaker that helps in announcing few messages. I am just learning and doing it now. My board is based on I.MX6, I am interfacing it to a an audio codec TLV320AIC32 via I2S.
My queries are:
DIN of processor should be connected to DIN of CODEC (slave) or DOUT of CODEC? Likewise for DOUT line as well.
If I will have to drive a 1W mono speaker, what needs to be taken care regarding drive capability (amplifier connections) and audio signals connectivity? Let me know about the calculations to be done.
What is bridge terminated load (BTL)? What difference does it bring to connectivity part?
