Main highlights

• •Applications: Commonly used in tremolo and vibrato circuits within guitar pedals and amplifiers to create distinctive modulation effects. It can also be employed in various other audio and signal processing applications where opto-isolation is required.
• •Opto-Isolation: The VTL5C3 provides effective electrical isolation between different circuit stages, preventing noise and interference from affecting sensitive components.
• •Improved Audio Clarity: Helps maintain audio clarity by isolating the control signals from the audio signal path, reducing distortion and unwanted artifacts.
• •Easy Integration: Designed for straightforward integration into existing circuits, making it a convenient choice for both DIY projects and commercial audio equipment.
• •Note: The LED is the side with shorter leads (longest lead is Anode / positive supply via resistor).
