Hi,
In lab, i have tested the chip with an bandgap, but the results confused me. when power supply ramps up, the output of bandgap will go down gradually.and this issue only happens when ADC begins to work. In only bandgap working mode,bandgap output is constant with power supply ramping up.
I don`t know why, pls give me some advice!
thank you in advance!
