5 Pieces LM567 LM567C LM567CN General Purpose Tone Decoder DIP8
By HLF
The LM567 is a general purpose tone decoders designed to provide a
saturated transistor switch to ground when an input signal is present
within the passband. The circuit consists of an I and Q detector driven
by a voltage controlled oscillator which determines the center
frequency of the decoder. External components are used to independently
set center frequency, bandwidth and output delay.
