1. Typical application

Note: a. R1 =1.2M

Ω (S.R.=6KHz ) , T ( transistor ) = ß > 150 ,S (speaker) =1/4W ,8Ω ; all typical.

b. R2=470

Ω ( typical ) to bypass extra current into base to get rid of waveform saturation on collector .

c. In order to avoid false ( or noise ) trigger.

1. To minimize the routing of trigger

signal.

2. The routing of trigger signal should be as far away as possible to speaker signal.

2. CDS application
