3.4.3.1 Analog Accuracy
The terminal measures the analog inputs using the GND pin as a reference. As the GND pin is shared with the power
supply, return current can create a voltage drop between the GND pin and the power supply, which in many cases

This value is dependent on the Lua services being used. This is not a hardware limitation. The hardware limit is specified by
the output bandwidth.
