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.

1. Guaranteed by characterization results.

2. Measured at VDD = 3 V ±10 mV. V110 ADC conversion result is stored in the TS_CAL2 byte.

3. Guaranteed by design.

4. Shortest sampling time can be determined in the application by multiple iterations.
