Product Summary

The LM567CM 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 LM567CM 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.
