Dear Sir, The one thing I love from TI is they always provide complete reference for every product design, application note, design guide, even evaluation board, project file and manufacturing file. it's help a lot of effort on development process. I have used several TI product, So I know my workflow should be when it comes to TI product based project like this. generally, I have became PCB designer since 2012, and has done lot of projects for various application, from Hobbyst to Military. I'm familiar with most of advanced PCB design technique like High speed digital communication, Differential pair, PCB antenna, Switching power supply, mixed signal(digital & analog), and many more. I will provide you manufacturing file as well as component selection According to your needs. let me know your thoughts about my proposal, let's discuss it over chat. Best Regards, Rijal

Audio Amplifier design proposal: The audio amplifier will require two 4.5V to 12V DC supply to power the audio amplifier with addition of a 3.3V or 1.8V digital supply and digital ground. The power supply will comprise of 220V to 12V converter with capacitor bank to filter noise in the power supply. The 3.3V or 1.8 V digital supply will use a DC to DC converter to reduce the 12V supply the desired voltage to power the digital point on the IC. The power supply will have capacitor bank filter notice and to reduce parasitic effect. It will use i2C for communication with raspberry pi. The audio amplifier parameter will be set in accordance with the client requirements. A PCB circuit design using KiCad and built to verify correct operation. It will be linked with the raspberry pi to check for correct operation. Destiny Innovations strives for excellence with optimal delivery. Choose us for your project problems.
