1. Guaranteed by design, not tested in production.

2. Quiescent mode refers to the state of the DAC a keeping steady value on the output, so no dynamic consumption is

involved.

3. Data based on characterization results, not tested in production.

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.
