Product Description ICL8038 High-Precision Adjustable Signal Generator DIY Kit 5Hz-400kHz This signal generator DIY kit is a professional product capable of generating sine waves/triangle waves/square waves/positive and negative sawtooth waves. This kit is a DIY kit and requires soldering and assembly by the user. Utilizes the ICL8038 and a high-speed operational amplifier for higher precision. Outputs sine waves/triangle waves/square waves/positive and negative sawtooth waves. Frequency range: 5Hz~400kHz; Duty cycle range: 2~95% (adjustable) Supports dual power amplifiers, eliminating the need for DC blocking capacitors, effectively suppressing high and low frequency signal distortion. Both frequency and amplitude are adjustable. Frequency adjustment features coarse and fine adjustment functions. All components are through-hole for easy installation. Power Supply Voltage: 12V~15V Low Distortion Sine Wave: 1% Low Temperature Drift: 50ppm/°C Output Triangle Wave Linearity: 0.1% DC Bias Range: -7.5V~7.5V Output Amplitude Range: 0.1V~11VPP (Operating Voltage 12V) Board Size: 7.8 x 5cm / 3.07 x 1.97 inches Finished Product Size: 8.7 x 6 x 1.7cm / 3.43 x 2.36 x 0.67 inches Material: FR4 + Acrylic Color: Black Package Contents: 1 * Low Frequency Signal Generator DIY Kit
