Fully Adjustable PWM Sawtooth/Square/ Sine/Triangular Wave Signal (Function) Generator Module..!
Description
The Pulse-Width-Modulation signal generator module can output square wave / rail-shaped wave / triangle / sawtooth / sine wave signals at a 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:
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 about 9.6V-Vpp (12V x 80%).
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 works with a 10-30V input supply voltage range. Voltage should not exceed 30V, otherwise it will burn the IC, if the voltage is below 10V, then the module will not have a waveform at the output.
3. About current drive capability and supply current: The output current drive capability of the output signal is about 10mA, power supply current should be 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.
