Four common audio output modes of voice chip

Voice IC is generally divided into four audio output modes. But there are only two common ones. What are the four? They are: current DAC audio output mode, dual PWM Direct Push audio output mode, voltage DAC audio output mode and class a/b output mode. Let’s talk about their advantages and disadvantages. Current mode DAC […]

Simulation debugging on bare metal system

The title “simulated debugging” seems a bit mysterious. After reading, embedded firmware developers may have cognitive dissonance; But believe me, it will make sense in the future. The title implies the task of processing signals processed in the microcontroller. Many tasks involving small MCUs are related to processing raw signals from sensors such as microphones, […]

How to realize current mode control of LLC in digital control system

All this starts with fan7688 control IC. Since I learned this control method of “resonance current integration”, I have been considering how to realize LLC current mode control in digital control system. Needless to say, the advantages of current mode control are much better than voltage mode LLC in terms of audio immunity. In particular, […]
