ADS7952: Analog input problem

Part Number: ADS7952

Hello Team

If one channel input higher than Ref value, but lower than the supply, what will happen? If it will damage the chip?

Now, the other channels will get the wrong value, could you give more information about it?

Thanks

  • Hello Xiao

    I do not suspect input voltage greater than VREF but less than VA will damge the device. Can you please confirm which input full scale span customer is using. Is it 1x VREF or 2 xVREF. What is the reference voltage and VA values.

    When you say other channel gives wrong value, can you please elaborate more about the use conditions such as input voltages applied on channels, expected code , wrong code value.etc

    Thanks & Regards
