12.Typical Application Circuit

Typical Application Circuit 1

For applications with interference or radiation interference on the supply line, a series resistor RV and

two capacitors CP and CL are placed near the sensor (typical application circuit 2).For example：RV=100Ω,CP

＝10nF and C

L＝4.7nF。

RL is an open drain pull-up resistor, which must be placed near the input end of the

host controller to enable wire break detection.
