(1) Supply current can rise-up to 20 mA max. in the 3-4 volts Vdd range.
(2) Start-up time : when the wheel has started spinning, the output signal appears after a few teeth but a
delay up to 150 ms could be seen before the highest accuracy/repeatability.
(3) The frequency is linked with the first order high pass filter with a cut-off frequency smaller than 20 Hz.
