TLE4946-2L

Specification

Attention: Stresses above the max. values listed here may cause permanent damage to the device.

Exposure to absolute maximum rating conditions for extended periods may affect device

reliability. Maximum ratings are absolute ratings; exceeding only one of these values may

cause irreversible damage to the integrated circuit.

1) To operate the sensor at the max. switching frequency, the value of the magnetic signal amplitude must be 1.4 times higher

than for static fields.

This is due to the - 3 dB corner frequency of the low pass filter in the signal path.
