AS3340 Ultra Low Frequency Application Note

Applies to AS3340, AS3340A, AS3345, AS3345A

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