Electrical characteristics
Figure 30. 12-bit buffered /non-buffered DAC
1. The DAC integrates an output buffer that can be used to reduce the output impedance and to drive external loads directly

without the use of an external operational amplifier. The buffer can be bypassed by configuring the BOFFx bit in the
DAC_CR register.
Temperature sensor characteristics

1. Guaranteed by characterization, not tested in production.
2. Measured at V
3. Guaranteed by design, not tested in production.
4. Shortest sampling time can be determined in the application by multiple iterations.
