What makes AKM different ?

There are many audio ICs other than Asahi Kasei Microdevices (AKM) around the world. So which IC should be selected?
One of the important factors is the sense of security that cannot be offered only from the specifications in the data sheet when customers are examining a product. 
Here, we will introduce the reasons why AKM audio ICs are so popular.
