RE46c128 Typical Application
Notes:
Figure 2
Pins 1 and 4 are not used.
External resistors on pin 13 can be used to adjust the alarm threshold.
R3, R4 and C1 are typical values and may be adjusted to maximize sound pressure.
C2 should be located as close as possible to the device power pins.
Route the pin 8 PC board trace away from pin 7 to avoid signal coupling.
