In the datasheet of AD5162, we can see 2ch, and first channel is shown by A1/W1/B1, but second channel only shows W2 and B2 and none for "A2". There is no pin assigned to "A2" in pin assignment.
How should I think about A terminal for this second channel ? Is it shared with other pins or A1 pin ?
Sorry to this fundamentals, but your helps would be very muchappreciated.
