8 / 18 page Sensors 8 Freescale Semiconductor MC146010 Figure 5. Typical Battery Powered Application # Values for R4, R5 and C6 may differ depending on type of horn used. * C2 and R13 are used for coarse sensitivity adjustment. Typical values are shown. † R9 is for fine sensitivity adjustment (optional). If fixed resistors are used, R8 = 12k, R10 is 5.6k to 10k and R9 is eliminated. ** Components necessary to utilize IMF feature.
