Part Number: ADS1018EVM

Dear E2E,

It is being tested by connecting with PC as below.

We tried to measure the room temperature using K type thermocouple, but the register value does not change.(3.3V operation)

AIN0 : Positive

AIN1: Negative

Can you help me?

Thank  you!

    Hello,

    What is the output range of the temperature sensor? It would be helpful if you can probe the AIN0 pin and send a scope capture. 

    It also looks like you have AIN0 set up as the positive input. Can you confirm that the temperature sensor is connected to the EVM correctly?

    Regards,
