Power amplifier/operational amplifier in ESP32
in the data sheet its written
''The output of the power amplifier is also adjustable''
how can i do this ? where can i find the option for it ?
i also want to measure the power consumption of Power amplifier/operational amplifier in ESP32

ESP32 frequency
how can we change the frequency of ESP32 for example there is an option of XTAL crystal frequency 40 MHz and 26MHz. but anyone knows if we can change it using PLL?
