Applications Spotlight - SmartPhones and PDAs
Smart phones and PDAs present challenges to a designer. AKM integrated codecs include sophisticated analog routing for Bluetooth
and car-cradle compatibility, remote button detection when using hands-free modes and reducing the number of external components
required by our solutions. The table on the right simplifies product selection. Look for the integrated features desired along the lefthand
side of the table, and then select the parts that are the best fit for your application. This is yet another example of how AKM
makes integrated audio easy!
