----------------------------------------------------------------------------------------------------------------------
1. The level of the analog signal is related to the reference voltage setting;
2. The digital signal level is 0~5V.
3. The driving capacity of the output digital signal is up to 10mA.
4. The analog interface terminal is electrically isolated from the power supply output
terminal.
