Hi,

What is the total calculated sensor drift in mT for temperature range -40 to 125 °C as per table 11 given in the datasheet.

What is LSB12/mT, is it equal to 0.098mT

Hi @rajkumarjain_87,

1. The sensitivity (LSB12/mT) for the sensor is given in table 11 of the TLV493D-A1B6 datasheet and the value is 10.2 LSB12/mT. This value is given for the temperature of 25 °C.  In the query by sensor drift if you mean the sensitivity drift, it is given in table 12 for the operating temperature range -40 to 125 °C and the value is ±20 %.

2. The value of 0.098 mT/LSB12 is the resolution for 12-bit readout and you can refer to an example calculation given after table 10 for calculating the magnetic field. 

Thanks and regards

George
