Product Summary

The LM567 is a general purpose tone decoder designed to provide a saturated transistor switch to ground when an input signal is present within the passband. The circuit LM567 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. The applications of LM567 are: Touch tone decoding, Precision oscillator, Frequency monitoring and control, Wide band FSK demodulation, Ultrasonic controls, Carrier current remote controls, Communications paging decoders.
