TPL0102-100: accuracy of this product ?

Part Number: TPL0102-100

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% (80k 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. 

    Best,
