LM567-LM567C Pdf资料

应用功能： Tone Decoder 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 independentlyset center frequency, bandwidth and output delay.
