Application Circuit
A typical Application Circuit for the AS8413 is presented at Fig. 8, where a 400 kHz oscillator with
external ceramic resonator is built for each IC. This circuit is suitable to be used in a microcon-
troller-based alarm system.
Optionally, the microcontroller could synthesize a 40 kHz for the ICs, decreasing component
count and power at the system level. The digital sensitivity also can be controlled, in specific
applications.
If access to all the signalling outputs of both ICs is provided, the alarm system will be able to
identify the kind of disturbance detected and the region where it occurred.
