Hello
My customer designed the key input circuit with adc101c021 as the attached figure.
However, with the "Steering_key" line open, the Vin voltage is dropped to about 0.8V.
Does this adc not use Vin port in a pull-up configuration?
Is there another part circuit configuration or something wrong, or should I set the Registor configuration?
