Hi.
I search information about ADC of Orange Pi 2G OIT, in the RDA8810PL datasheet said: "The GPADC module controls the analog module of general purpose analog to digital converter, which is capable of measuring one of 5 analog external inputs of the chip" and after said " GPADC is active periodically at a variable rate and measures all the enabled channel (up to 5) each time"... it's confusing.
Don't said if the ADC have a Sample & Hold or more information... The sampling of the 5 input is simultaneous sampling or is sequencial sampling? (see the picture)



Thanks!
