Details

This ADC Tibbit is based on the LTC2309 12-bit ADC with I2C interface. Only four channels of this

ADC are used by the Tibbit. The analog front end of the module allows you to measure signals in

the -10V to +10V range. All measurements are with respect to the system ground.

This may not be an issue when running a conversion loop for a single ADC channel. You will have to ignore the rst result in these cases: Discard the rst ADC result after the channel change. Only the second measurement will bring you the conversion data for the newly selected channel.
