kdx 01 low frequency square wave signal source frequency signal generator of adjustable duty ratio instead of ne555 купить по лучшей цене

DIY ICL8038 Function Signal Generator Module Sine Square Triangle Wave Output KIT Feature: With excellent performance ASIC chip function generator ICL8038, add a small amount of resistive and capacitive components, can produce sine, triangle and square wave, and the frequency of the signal, duty cycle, adjustable distortion sine wave. Notice: Requires a certain DIY ability, you need to soldering the kit yourself : ) Description: ICL8038 pin functions: Pin 1, Pin 12: sine waveform adjusting terminal; Pin 2: sine wave output; Pin 3 : triangle wave output; Pin 4 Pin 5 : the frequency and duty cycle (or waveform asymmetry) adjustment; Pin 6 : V + the positive power supply; Pin 7 : Frequency Offset; Pin 8 : Frequency adjustment input terminal; Pin 9 : square wave output. This is an open collector output terminal, work should take a load resistor to the corresponding positive power supply terminal from the pin, to get a TTL-compatible square-wave output, the load resistance must be connected to + 5V power supply; Pin 10 : timing capacitor terminal; Pin 11 : V- negative power supply terminal or the ground. When Use positive and negative power supply, Pin 11 to the negative supply, the output waveform are symmetrical with respect to 0 V; When use a single positive power supply, Pin 11 grounded, the output waveform is unipolar, uniform voltage is + VCC / 2; Pin 13 and Pin 14 : Empty Pin. The kit is designed for a frequency range is 50-5KHz, two bands with using a switch S to switch, RP1 is the frequency adjustment, RP2 is the duty cycle adjustment, RP3 is a sine wave distortion adjustment. Circuit uses 12V single power supply, input from the X1; X2, X3 is a waveform output side, you can use oscilloscope to observe three output waveforms. Model: ICL8038 Input: 12V DC Frequency range: 50-5KHz, Size: 6cm*4.5cm*0.2cm Package Included: 1 x DIY ICL8038 Function Signal Generator Module Sine Square Triangle Wave Output KIT
