Thank you for question,

You can use IN+ Channel2 only in Single-ended Mode. In order to activate it you need to change Channel selector from VDD to PIN16, the channel selector is a digital input where HIGH selects IN+ Channel1 (PIN8) and LOW selects IN+ Channel2 (PIN9). So when PIN16 is LOW you will use IN+ Channel2. If something is unclear, please see the attached file, hope it will be heplful.

Best regards,

Thank you very much, it is

Thank you very much, it is clear. 

But another question, it is not possible connect In+Channel 1 IN+channel2 and IN+ Channel to different Pins at the same time?

Thank you very much

There is an analog multiplexer on input of PGA block (VDD/PIN16 select the channel), so you can connect to the different PINs, but only one can be chosen as IN+.
