5. Difference between the value measured at Code (0x800) and the ideal value = V
6. Difference between the value measured at Code (0x001) and the ideal value.

Difference between ideal slope of the transfer function and measured slope computed from code 0x000 and
0xFFF when buffer is OFF, and from code giving 0.2 V and (V
without the use of an external operational amplifier. The buffer can be bypassed by configuring the BOFFx bit in the
DAC_CR register.
