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