Features:
The minimum output amplitude of sine wave and triangle wave, sawtooth wave is about 30% of power supply peak voltage, and output amplitude of PWM, square wave, rectangular wave is about 80% of power supply peak voltage.
Adjustment range of output amplitude potentiometer  is 30% - 80%VPP of power supply voltage. Note that if the gain changed by potentiometer is too big or too small, wave type will output variant distortion.
Power supply voltage is 10V to 30V, recommended working voltage is 12V to 18V, which will get a better effect.
Output current driving ability is about 10mA, and power supply current should be more than 30mA.
Output frequency is adjusted piecewise by jump pins switching oscillation capacitors.The external oscillation capacitors are C1, C3, C4 and C2, C29, of corresponding capacitance respectively:100pF, 1nF, 10nF, 0.1uF, 1uF.
