Known Issues 

9.1 

Switching Transient Artifacts of Current Measurement Circuit  

When the current measurement circuit changes scale, it presents some small or large voltage step 
on the A/D converter inputs. An ideal converter (infinite bandwidth) would produce a single spike at 
the point of switching. But since the converter is not ideal, it produces a ringing like waveform (

Figure 

52

)

 

Figure 52: A/D Converter Distortions 

In 

Figure 52 

we can identify three types of ringing artifacts created by the A/D converter: 

● 

Switching from low to high scale (1) 

● 

Not switching, but instead a signal with very steep fall is present (2) 

● 

Switching from high to low scale and then another switch Low-High-Low creates this exaggerated 
false peak (due to a large difference of the DC levels of the two C/V converters, 3) 

9.2 

Push Button SW3 

SW3 is enabled on DA145xx DEVKT-P PRO-MB by P1_1. By default, this signal is not driven from 
DA14531. Consequently, jumper J19:4-5 is not required in DA14531 DK PRO. 

 

Figure 53: Disable SW3. Remove Jumper from J19:4-5
