Table 4 Electrical Characteristics (cont’d)
All values specified at constant amplitude and offset of input signal, over
operating range, unless otherwise specified.
Typical values correspond to VCC = 12 V and TA = 25°C

1) Magnetic amplitude values, sine magnetic field, Limits refer to the 50% critera. 50% of pulses are missing or
wrong. Valid in calibrated mode only.
2) The sensor requires up to nstart magnetic switching edges for valid speed information after power-up or after a
stand still condition. During that phase the output is disabled.
3) One magnetic edge is defined as a montonic signal change of more than 3.3 mT
4) Direction signal is given already during uncalibrated mode. Assembly Bit information is only provided in
calibrated mode
5) High frequency behavior not subject to production test - verified by design/characterization. Frequency above
2500 Hz may have influence on jitter performance and magnetic thresholds. DR-R pulse length will be cut off
above app. 3.3 kHz Therefore direction detection may not be possible anymore at high frequency.
6) During fast offset alterations, due to the calibration algorithm, exceeding the specified duty cycle is permitted
for short time periods
7) Not subject to production test- verified by design/characterization
