Integrated Circuit - AS3109D, VCF, Alfa, SOIC-16
The AS3109 is Alfa’s version of the Roland IR3109 VCF in an SOIC package. The AS3109 is a high performance voltage controlled four-pole filter. The four independent sections may be interconnected to provide a wide variety of filter responses, such as low pass, high pass, band pass and all pass. A single input exponentially controls the frequency over a range greater than 15 octaves with little control voltage feedthrough. AS3109 features high input impedance buffers.
Features
- Voltage controllable range – 15 octaves
- Accurate exponential frequency scale
- High input impedance buffers
- Wide transconductance range
- Low input offset voltage
- Low control voltage feedthrough - 45 dB typical
Applications
- For electronic music
