Ain bit resolution

[MikeW48]

Does anyone know what the bit resolution is for the Ain analog input?
8, 12, or 16 ?

@MikeB Do you know?

It is 8 bits, mainly because the SPort protocol for the value only sends 8 bits.

Thought so but couldn't find it listed anywhere.
That limits its use for a remote telemetry application I was thinking of using FrSky data logging and the graphing feature of OpenTX.
Pretty cheap given I have all the parts laying around..

Thanks a Bunch,

Looking at the values in one of my Log-files the telemetry values should have more than 8-bit.

So if Ain2 really has only 8 bits this may be because of the used sensor-hardware in the receiver.
Ain2 is mainly used to measure the voltage of the battery and that is varying drastically during flight. (So there's no need for more bits I think)
