product description
1. The ICL8038 precision function generator is a monolithic integrated circuit chip made using advanced technologies such as Schottky barrier diodes. It has the advantages of wide power supply voltage range, high stability, high precision, and ease of use. It only requires external access. A few components can work, and square wave, triangle wave and sine wave can be generated at the same time. The frequency of the function waveform is controlled by internal or external voltage and can be applied to voltage-controlled oscillation and FSK modulator.
2. It has a low frequency drift when the temperature changes occur, and the maximum frequency drift does not exceed 50ppm / °C; It has a variety of function signal output such as sine wave, triangle wave and square wave; The sine wave output has less than 1% distortion; Triangle wave output With 0.1% high linearity; with a frequency output range of 0. 001Hz-1MHz; wide working change cycle, adjustable from 2% to 98%; high level output range, from TTL level to 28V; Easy to use, requiring only minimal external conditions.
3. The ICL8038 is a precision oscillation integrated circuit with multiple waveform outputs. Simply adjusting individual external components can generate low-distortion sine, triangle, and square wave pulse signals from 0.001 Hz to 300 kHz. The frequency and duty cycle of the output waveform can also be controlled by current or resistance. In addition, because the chip has an FM signal input, it can be used to frequency modulate low frequency signals.
1. The SMA head output port can output sine wave and triangle wave, and the output waveform switching is controlled by P5. As shown in the figure above, the jumper cap is connected to the left to output a sine wave, and the middle output triangle wave.
2. The square wave can only be output from P3, and it is not necessary to switch the waveform adjustment jumper cap (P5).
3. R8 is the duty ratio adjustment on the module, and R12 is the frequency adjustment.

Attention
Want to get the square wave signal can only be output from the waveform output port of the welding pin, and it is related to the input voltage of the power supply
Pay attention
Want to get the square wave signal can only be output from the waveform output port of the welding pin, and it is related to the power input voltage. For example, the power supply is 10V, and the peak-to-peak value of the square wave signal is 20Vpp.
