Digital-to-analog converter (DAC)
The 12-bit buffered DAC channel can be used to convert digital signals into analog voltage
signal outputs. The chosen design structure is composed of integrated resistor strings and
an amplifier in non-inverting configuration.
This digital Interface supports the following features:
●
●
●
●
Five DAC trigger inputs are used in the device. The DAC is triggered through the timer
trigger outputs and the DAC interface is generating it’s own DMA requests.
Fast low power comparators and reference voltage
The device embeds two fast rail-to-rail comparators with programmable reference voltage
(internal or external), hysteresis and speed (low speed for low power) and with selectable
output polarity.
The reference voltage can be one of the following:
●
●
●
Both comparators can wake up from STOP mode, generate interrupts and breaks for the
timers and can be also combined into a window comparator.
The internal voltage reference is also connected to ADC_IN17 input channel of the ADC.
Serial wire debug port (SW-DP)
An ARM SW-DP interface is provided to allow a serial wire debugging tool to be connected
to the MCU.
