26. ADC - Analog to Digital Converter

0 1 2 3 4
26.1 Introduction
The ADC uses a Successive Approximation Register (SAR) architecture, with a resolution of up to 12 bits at up to one million samples
per second (1 Msps). The integrated input multiplexer can select from external I/Os and several internal signals.

ADC - Analog to Digital Converter
Quick Facts
What?
The ADC is used to convert analog signals into a
digital representation and features low-power, auton-
omous operation.
Why?
In many applications there is a need to measure an-
alog signals and record them in a digital representa-
tion, without exhausting the energy source.
How?
A low power ADC samples up to 32 input channels
in a programmable sequence. With the help of PRS
and DMA, the ADC can operate without CPU inter-
vention in EM2 Deep Sleep and EM3 Stop, minimiz-
ing the number of powered up resources. The ADC
can further be duty-cycled to reduce the energy con-
sumption.
