what is the difference between two type numbers AD8610AR and AD8610BR?
I couldn't find it in the data sheet.
The A and B indicate the grades of the parts. Generally, the higher you go, the better the specifications. For the case of the AD8610, the B grades have lower offset voltage and lower offset voltage drift.
The differences will be in the specifications table on pages 3 and 4 under Input Characteristics.
I hope this helps.
Thank you very much Kris for your quick and kind reply.
