2.12.4 Buzzer Output
The buzzer output is a digital one. A buzzer can be directly connected between
this output and VBATT. The maximum current is 80 mA (PEAK). A diode
against transient peak voltage must be connected as described below.
R1 must be chosen in order to limit the current at I
C1 = 0 to 100 nF (depending on the buzzer type).
Recommended characteristics for the buzzer :
Type : electro-magnetic.
Impedance : 7 to 30 Ω
Sensitivity : 90 dB SPL min @ 10 cm
