6) Hall input setting
Hall input voltage range is shown in operating conditions.
Fig.89 Hall input voltage range
Adjust the value of hall element bias resistor R1 and R2 in Fig.90 so that the input voltage of a hall amplifier is input in
"hall input voltage range" including signal amplitude.
○
Reducing the noise of hall signal
Hall element may be affected by Vcc noise or the like depending on the wiring pattern of board. In this case, place a
capacitor like C1 in Fig.90. In addition, when wiring from the hall element output to IC hall input is long, noise may be
loaded on wiring. In this case, place a capacitor like C2 in Fig.90.
