Hello TI,
Im currently testing the DRV5053 sensor for a project, specifically the -11 mV/mT, -23 mV/mT, -45 mV/mT and the -90 mV/mT. My first question is if there is more documentation of the DRV5053 sensors, I need to collect as much info as possible. Most important things I need to know is the difference between single units and the differences between batches of sensors for example.
My next question is regarding the tests I have performed untill now. It seems all the sensors change their output values after the first saturation, I started noticing that the values of the first test I performed were lower than the tests i did after this first saturation. So i took a new sensor and did a test without saturation and noticed the values stay the same untill I saturate the sensor again in one of the following tests. this seems to happen both for the positive and negative sensitivity. In the added graph (top left window) you can see that the runs before saturation are different than the runs after saturation (there is a noticeable shift in values). I was wondering if there is any information about why this shift in values happens.
Thanks in advance!
