1. Data guaranteed by design, not tested in production.

2. VREF+ can be internally connected to VDDA and VREF- can be internally connected to VSSA, depending on the package.

Refer to Table 12: STM32F328C8 pin definitions for further details.

Figure 23 illustrates the ADC current consumption as per the clock frequency in single-ended and

differential modes.
