Figure 40. 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.

minimum value of 1.7 V is obtained with the use of an external power supply supervisor (refer to Section 3.15.2:
Internal reset OFF).
2. Guaranteed by design.
3. The quiescent mode corresponds to a state where the DAC maintains a stable output level to ensure that no dynamic
consumption occurs.
4. Guaranteed based on test during characterization.
