Hi team,
I use ADG704 to switch low voltage, the voltage on the channel is 0~3.3V, the power supply is 3.3V,The operating temperature -10~70°C, I put the PCBA into the chamber and test it, occasionally abnormal phenomenon with increasing temperature , the description as follow.
1. ADG704 seems to have large leakage current, the output voltage becomes smaller as the temperature increasing .
2. As the temperature increasing , there are some crosstalk on the channel1/2/3/4
When the temperature increase to 65°C and waiting for ten minutes, the failure is disappear.
Is this failure related to the operating temperature and humidity of the ADG704? I don't see any requirement of humidity on the datasheet, could you help to
confirm the requirement of humidity on ADG704.
Thank you.
kevin
