See other suppliers →Description
The LM567 is a general-purpose tone decoder designed to provide a saturated transistor switch to the ground when an input signal is present within the passband. The circuit consists of an I and Q detector is 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.
