Hello, we have a problem interpreting your newest release of the DAC121C085 datasheet (Revision Januray 2016). There are inconsistencies in Table1 regarding the I2C Addresses the device responds to the different assignements of A0 and A1. Something must be definitely wrong with the table. The Pin description specifies that A0 selects the lower 2 Bits, but table1 shows the same higher address where the lower address definitely is different. Could you please clarify which I2C addresses are assigned to the DAC121C085 regarding to the A0 and A1 pins ? Yours sincerely, Gerhard Oed]
