3.3 Operating Range
The following operating conditions must not be exceeded in order to ensure correct operation of the TLI4946xy.
All parameters specified in the following sections refer to these operating conditions unless otherwise mentioned.
3.4 Electrical Characteristics
Product characteristics include the spread of values guaranteed within the specified voltage and ambient
temperature range. typical characteristics are the median of the production (at V

2) To operate the sensor at maximum switching frequency, the value of the magnetic signal amplitude must be 1.4 times
higher than the static fields. This is due to the -3 dB corner frequency of the low pass filter in the signal path.
