Keep inputs below 1mA to avoid unhappy transistors.
The core of many compressors, limiters, and synth modules, a VCA allows you to control the amplitude of a signal with a control voltage (CV). 2. Voltage-Controlled Filter (VCF) lm13720
A classic application is the compressor pedal (like the MXR Dyna Comp), where the output signal is used to drive the IABCcap I sub cap A cap B cap C end-sub pin, reducing gain when the input is too loud. Tips for Working with the It typically runs on Keep inputs below 1mA to avoid unhappy transistors
Utilize the linearizing diodes to significantly reduce harmonic distortion. Conclusion Voltage-Controlled Filter (VCF) A classic application is the
Two OTAs in one 16-pin package, sharing common supplies but operating independently.
