PWM Sawtooth Square Wave / Sine Wave / Triangle Wave Signal Generator

PWM Sawtooth Square Wave / Sine Wave / Triangle Wave Signal Generator

The PWM signal generator module can output square wave / rail-shaped wave / triangle / sawtooth / sine wave signal, the frequency range of 10Hz~300KHz, adjustable duty cycle of 2%~98%. Adjustable output signal frequency wave crest arc, trough arc, rise time, fall time and so on.

Note: Adjust the capacity of C29 can be changed, the output pulse frequency variable range. Up to 300KHz output.


1. About the output amplitude: sine and triangle wave, sawtooth minimum output amplitude is about 30% of the supply voltage peak, and PWM, square wave, square wave output amplitude is about 80% of the supply voltage peak.

For example: 12V power supply, then: the output amplitude sawtooth, sine, triangle wave is 4V-VPP (12V x 30%) or so, the output amplitude PWM, square wave, rectangular wave is 9.6V-VPP (12V x 80%) about.

Output amplitude adjustment potentiometer adjustment range is: supply voltage 30%~80% VPP One thing to note is that if the gain adjustment potentiometer is too big or too small change, it will output variant wave distortion.

2. About power supply voltage. Recommended operating voltage is 12~18V, so the effect will be better. But this module is to supply 10-30V can work, but must not exceed 30V, otherwise it will burn IC, if the voltage is below 10V, then the module will no wave output.

3. About current drive capability and supply current, the output current drive capability of the output signal is about 10mA, power supply current can be as long as there are more than 30MA.

4. About output frequency. Frequency is determined by the board jumpers to implement segmentation oscillation capacitor switching frequency adjustment. External shocks capacitance C1, C3, C4, C2, C29 corresponding capacitance are: 100PF, 1NF, 10NF, 0.1UF, 1UF five bands of frequency adjustment range, adjacent frequency of 10 times.

Also, if you need to get a high-frequency signal 80KHz~300KHz, to do the following:

A. Department must jumper cable leads from the switching signal.

B. external shocks capacitor to be replaced less than 100PF, the smaller the capacitance, the higher the frequency.

5. About the output waveform adjustments.

A. Triangle, (positive and negative) to adjust the sawtooth.

B. sine adjusted.

Jump sine jumper position.

Adjustments along time potentiometer can change the slope of the sine wave is positive clockwise or counterclockwise direction.

Adjusting frequency potentiometer can change the frequency of the sine wave.

Adjust the curvature of the sine wave peaks, valleys radian sine wave can change potentiometer peaks and troughs radian radian shape. It should be noted that the function of the two potentiometers functions are adjusted too far in the exchange. That is, the peaks will become standard tune trough, the trough will become standard tune peaks, but are likely to affect the performance of wave.

C.PWM. Square wave, rectangular wave adjustments.

Jumper jump PWM. Square wave, rectangular wave position.

Adjustments along time potentiometer can change the PWM. Duty cycle square wave, rectangular wave.

Adjusting frequency potentiometer can change the PWM. Frequency square wave, rectangular wave.

Accelerating wave potentiometer can be fine-tuned. Under normal circumstances, you can not ignore.

What is Bulk Rate? BulkRate is a semi-wholesale system with items priced separately from retail. When you use bulk rates, a flat $1.70 registered air mail fee will automatically be added to your cart to ensure delivery of package. While BulkRate's intention is to offer cheaper prices when you buy in bulk, because it is priced separately it on occassions show a higher than retail price. That's why we ask you to enter BULKRATE as a coupon code to manually activate the rates. You can always opt not to use the bulk rates.
