DAC (digital-to-analog converter)

The two 12-bit buffered DAC channels can be used to convert two digital signals into two
analog voltage signal outputs. The chosen design structure is composed of integrated
resistor strings and an amplifier in non-inverting configuration.

This dual digital Interface supports the following features:

•

Two DAC converters: one for each output channel

•

8-bit or 12-bit monotonic output

•

Left or right data alignment in 12-bit mode

•

Synchronized update capability

•

Noise-wave generation

•

Triangular-wave generation

•

Dual DAC channels, independent or simultaneous conversions

•

DMA capability for each channel (including the underrun interrupt)

•

External triggers for conversion

•

Input reference voltage V

REF+

Eight DAC trigger inputs are used in the STM32L100RC device. The DAC channels are
triggered through the timer update outputs that are also connected to different DMA
channels.

3.12

Ultra-low-power comparators and reference voltage

The STM32L100RC device embeds two comparators sharing the same current bias and
reference voltage. The reference voltage can be internal or external (coming from an I/O).

•

One comparator with fixed threshold

•

One comparator with rail-to-rail inputs, fast or slow mode. The threshold can be one of
the following:

–

DAC output

–

External I/O

–

Internal reference voltage (V

REFINT

) or a sub-multiple (1/4, 1/2, 3/4)

Both comparators can wake up from Stop mode, and be combined into a window
comparator.

The internal reference voltage is available externally via a low-power / low-current output
buffer (driving current capability of 1 µA typical).

3.13 System

configuration controller and routing interface

The system configuration controller provides the capability to remap some alternate
functions on different I/O ports.

The highly flexible routing interface allows the application firmware to control the routing of
different I/Os to the TIM2, TIM3 and TIM4 timer input captures. It also controls the routing of
internal analog signals to ADC1, COMP1 and COMP2 and the internal reference voltage
V

REFINT
