Introduction to PCM5102:
It is a 32-bit stereo audio frequency to analog conversion chip (DAC) from TI company.
The chip integrates a 2.1Vrms level output, which can drive headphones with a resistance of up to 320 ohms.
The dynamic range has reached 112dB.
Without output coupling capacitors, there is no need to worry about finding expensive coupling capacitors.
