KMZ60 about start-up angle error

abcdchan15 — Mon, 09 Jan 2017 05:37:18 GMT

I have question about KMZ60 application. I want to use it to detect the position in Electronic throttle body. The datasheet mention about " start-up angle error", the error is bigger with TC link to VCC. Did i need to set the throttle to zero point to learn the zero point angle value for adjusting the error with every start-up, or just need once before leaving the factory.

Hello Jianwei,

The KMZ60 does not have an automatic offset compensation integrated. That means, when you start the device, the output offset needs to be calibrated by your acquisition system.

Under standard conditions, it is sufficient to determine one time the Offset and TC-offset in fab and correct the KMZ60 signals with this offset vs. temperature characteristics.

Best regards,

Tomas
