Digital-to-Analog Converter (DAC)

[δΈ­ζ–‡]

When using DAC output for ESP32-S2-Saola-1, the power supply is 3.3 V. But the actual tested voltage is only 3.1 V. Why?

Due to the presence of internal voltage drop and inter-chip differences, even when powered by 3.3 V, the actual maximum output is only around 3.2 V.
