codec chips
An AUDIO CODEC chip (WM9731L by Wolfson) have pin outs:
1. SPKR
2. SPKL
3. OUT 3
4. OUT 4
5. GND
What is the difference between the SPKL/R pin and OUT 3/4 pin? Does it mean that I need a speaker with 3 terminals (for SPKL/R, OUT3/4 and GND)? Can someone help me regarding this coz Ive only encountered speakers with on;y 2 terminals.
Thanks!
