Alfa Rpar - AS3394ED - µP Controllabel Synthesizer Voice
Product number:
103132SO24
Product information "Alfa Rpar - AS3394ED - µP Controllabel Synthesizer Voice"
The AS3394E is a complete analog music synthesizer voice-on-a-chip intended for software control by a microprocessor system. Included inside the compact 24 pin package is fully temperature compensated, wide range, voltage controlled oscillator providing sub-oscillator, triangle, saw-tooth, and pulse waveforms; a voltage controlled mixer for adjusting the balance between the internally generated VCO waveforms and any external signal; a dedicated four-pole low-pass voltage controlled filter with voltage controlled resonance; a modulation amount VCA for modulating the filter frequency by the triangle waveform output of the VCO; and a final VCA for allowing the output to be enveloped. Envelope control for both the VCF and final VCA may be provided by either a hardware envelope generator such as the AS3310 or through software.
All eight control inputs are provided with internal very high input impedance, low bias current buffers. Thus interface to a microprocessor system may be accomplished simply with a single DAC, 4051-type CMOS multiplexer, and 8 hold capacitors.
Requiring a bare minimum of other external components, the AS3394E is ideal for low cost polyphonic or polytimbric musical instruments featuring rich, analog sound.
AS3394EA is an improved version of AS3394E.
Features:
• Complete synthesizer Voice on a Chip
• Sample & Hold buffers on-chip for easy interface to a μP
• Fully temperature compensated VCO
• Independently selectable VCO waveforms
• Sub-oscillator output
• Separate saw-tooth output
• Separate VCO and filter sections allowing design flexibility
• Constant Loudness vs Resonance VCF
• Rich Sounding VCF Design
• Filter FM routing for more Timbres
• Low Noise, Low Feedthrough VCA

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.
