Electrical characteristics
4. Difference between measured value at Code i and the value at Code i on a line drawn between Code 0 and
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.
7.
8. In buffered mode, the output can overshoot above the final value for low input code (starting from min value).

last Code 4095.
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.
