General PCB design guidelines
To obtain best results, some general design and layout rules should be followed when
designing the application PCB to shield the noise-sensitive, analog physical interface from
noise-generating CMOS logic signals.
●
Use separate digital and analog planes. The analog ground plane should be connected
to the digital ground plane via a single point on the PCB.
●
Filter power to the analog power planes. It is recommended to connect capacitors, with
good high frequency characteristics, between the power and ground lines, placing
0.1 F and optionally, if needed 10 pF capacitors as close as possible to the STR7
power supply pins and a 1 to 10 F capacitor close to the power source (see
●
The analog and digital power supplies should be connected in a star network. Do not
use a resistor, as VDDA_ADC is used as a reference voltage by the A/D converter and
any resistance would cause a voltage drop and a loss of accuracy.
●
Properly place components and route the signal traces on the PCB to shield the analog
inputs. Analog signals paths should run over the analog ground plane and be as short
as possible. Isolate analog signals from digital signals that may switch while the analog
inputs are being sampled by the A/D converter. Do not toggle digital outputs near the
A/D input being converted.
Software filtering of spurious conversion results
For EMC performance reasons, it is recommended to filter A/D conversion outliers using
software filtering techniques.
