Alfa Rpar - AS3381D - Dual Low Noise Voltage Controlled Amplifier(VCA)
Product number:
103131SO8
Product information "Alfa Rpar - AS3381D - Dual Low Noise Voltage Controlled Amplifier(VCA)"
AS3381 is a dual low noise voltage controlled amplifier, with linear scale, intended for applications requiring high audio performance in a small space. AS3381 contains two gain cells with extremely low noise for signal-to-noise ratio better than 100 dB, low distortion with less than 0.3% THD, and low control feedthrough for "pop" free performance when gain modulated.
AS3381 is also extremely easy to use, requiring few external components and no external trimming to meet their excellent performance. The signal inputs are summing node inputs for convenient signal mixing; and the control voltage inputs, covering over 100dB with a 5 volt nominal range, are referenced to ground when the outputs feed virtual ground summing nodes. The current mode outputs offer additional flexibility, allowing AS3381 to be used in high performance VC filters and waveform generators as well as amplifiers.
Features:
• two high performance VCAs
• extremely low noise: > 100dB S/N ratio
• low distortion: <0.3% THD
• low feedthrough: <0.3% of full scale output
Applications:
• voltage controlled stereo levels
• programmable mixers
• high performance AGC, compandors and limiters
• voltage programmable filters and oscillators
• for electronic music

Safety Instructions for Electronic and Mechanical Components
Intended Use:
• Electronic components, including potentiometers, knobs, switches, connectors, resistors, capacitors or integrated circuits (ICs), are designed for use in electronic circuits and devices.
• Use these components only for their intended purposes in electrical and electronic applications, according to their specified voltage, current, and environmental conditions.
• Any use outside the intended applications may result in malfunction or safety risks.
Handling and Installation
Installation:
• Handle electronic components with appropriate tools, such as tweezers, to avoid physical damage or exposure to electric shock.
• Ensure that the components are installed in the correct orientation and according to manufacturer specifications to avoid malfunction or damage to the circuit.
Storage:
• Store components in a dry, cool, and static-free environment to avoid damage from moisture, extreme temperatures, or electrostatic discharge (ESD).
• Avoid direct exposure to sunlight, which could affect component stability and performance.
Protection from Static Electricity:
• Use antistatic equipment (e.g., wrist straps, ESD mats) when handling electronic components to prevent electrostatic discharge, which can damage sensitive devices like ICs.
Compatibility:
• Make sure electronic components are compatible with the circuit in terms of voltage, current, and other technical specifications.
Warnings
Electrical Shock Hazard:
• Some components can retain charge even when disconnected. Use appropriate tools and take precautions when handling components to minimize the risk of electric shock.
Burn or Fire Risk:
• Overloading or misusing electronic components may result in overheating, which could lead to burning or fires. Ensure that components are used within their specified voltage and current ratings.
Danger from Misuse:
• Incorrect handling or use outside specified limits can damage the components or affect the performance and functionality of connected devices. Only use components within their specified tolerances and conditions.
Choking Hazard:
• Small electronic components can pose a choking hazard if swallowed. Keep components out of reach of children.
