Description
The LM567 and LM567C are 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.
