Hello, Team
according to datasheet page.12
"The TPL0102-100 has an end-to-end resistance of 100 kΩ with a 20% end-to-end resistance tolerance."
it makes TPL0102 20% less accurate, am i understand it right ?

Hi King,
This means that the end to end resistance of the digital potentiometer can vary by 20% (80kΩ to 120kΩ). This is important if your application depends on the resistance value such as variable resistor applications when the TPL0102 is used in rheostat mode:
You can see that Rtot will be affected by the 20% end-to-end resistance tolerance.
It is not as important if your application depends on the ratio of wiper-to-H and wiper-to-L values in voltage divider mode:
The Vw voltage is not impacted by the 20% end-to-end resistance tolerance.
