Figure 59. 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.
