Mali generator TTL signala frekvence do 200KHz i promenljive sirine impulsa.

1 , Size : 3.1CM * 2.2CM
1, the main chip : NE555;
2 , Input voltage : 5V-15VDC. 5V power supply , the output current can 15MA around ; 12V power supply, the output current can 35MA around ;
3 , the input current : ≥ 100MA
4 , the output amplitude : 4.2V V-PP to 11.4V V-PP. ( Different depending on the input voltage , the output amplitude will be different )
5 , the maximum output current : ≥ 15MA (5V power supply , V-PP greater than 50% ), ≥ 35MA (12V power supply , V-PP greater than 50% )


Three Advantages:
1, the output with LED indication , there is no output straightforward ( low LED volume, high LED off frequency is relatively low , the LED flashes ) ;
2, the output level selectable frequency range , the output frequency is more continuously adjustable ;
LF file : 1Hz ~ 50Hz
IF file : 50Hz ~ 1kHz
High-frequency file : 1KHz ~ 10kHz
HF file : 10kHz ~ 200kHz
3, the output duty cycle can fine-tune , duty cycle and frequency is not separately adjustable , adjusting the duty cycle will change the frequency ;
4, the output frequency is adjustable;
Period T = 0.7 (RA +2 RB) C

RA, RB is 0-10K adjustable;

Low profile when C = 0.001UF;
IF stalls C = 0.1UF;
High-frequency file C = 1UF;
HF stalls C = 100UF, so the frequency of the waveform buyers can calculate their own
