DIY ICL8038 Multi-Function Low-Frequency Signal Generator Kit

DIY ICL8038 Multi-Function Signal Generator Kit

This is a soldering kit based on the ICL8038 precision waveform generator IC. It is designed to produce three types of low-distortion waveforms: sine, square, and triangle. The frequency and duty cycle are adjustable via onboard potentiometers. This is a through-hole soldering kit; all components are provided loose and must be assembled by the user.

Product Features

• Outputs three standard waveforms: Sine, Square, and Triangle.
• Adjustable frequency range covering 10Hz to approximately 450kHz.
• Independent potentiometers for adjusting frequency, duty cycle, and sine wave distortion.
• Supports both single power supply (9V-12V) and dual power supply configurations.
• Low-drift performance with temperature changes.
• Standard 2.54mm pitch headers for signal output and power input.

Waveform Output Characteristics

Assembly Requirements

This kit consists entirely of through-hole components. Users must provide their own soldering tools. It is recommended to use a socket for the ICL8038 IC to prevent heat damage during soldering.

• Soldering iron and solder wire
• Wire cutters (for trimming component leads)
• Multimeter (for verifying power input before inserting the IC)
