Moreover, the book has an appendix that contains a case study. There is a recommendation that it should be mounted with a Surface Mount type mount. I have embedded a 64-VFQFN Exposed Pad case with it in order to protect it. A 4 channel is present on the device. You can refer to Audio Processor functions in this part. Devices can be applied in Communication Systems directions. 64-QFN (9x9) packages the device.
