I tested different 24bit DACs on my Teensy 4.1.
1. PT8211 16-bit DAC
2. PCM5102A 32-bit DAC Burr Brown
3. ES9032P 24Bit DAC HIFIberry Board
Here are spectrum analysis from DACs. The sample rate for PT8211 to 44.1KHz and and the others are 88.2KHz.
I measured the frequency spectrum of the DAC converter with a measuring Sine tone of 440 Hz from Teensy.
PT8211 shows large distortions in the overtones. PCM5102A and ES9032 are very good and have very little noise.
PT8211
Samplerate: 44.1KHz (PT8211 Teensy driver)
PCM5102A
Samplerate: 88.2KHz (I2S1 Teensy driver)
ES9023P
Samplerate: 88.2KHz (I2S1 Teensy driver)
PT8211
PCM5102A
ES9023P
