3340 VCO Ultra Low Frequency Technical Note

AS3340 Ultra Low Frequency

Application Note



Applies to AS3340, AS3340A, AS3345, AS3345A

In typical LFO applications the value of capacitor CF can be in the range 1nF to 50nF. If an ultra low frequency is neeeded, CF must be increased to 1.0uF and some changes in the circuit design must be done. Note the 39K resistor added to pin 6:
