Juried Engineering LM567CN/NOPB LM567CN LM567 IC Tone Decoder & 8-Pin DIP Sockets with Machined Contact Pins Breadboard-Friendly (Pack of 5)($18.98Value)

Description

20 to 1 frequency range with an external resistor Logic compatible output with 100 mA current sinking capability Bandwidth adjustable from 0 to 14% High rejection of out of band signals and noise Immunity to false signals The LM567 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.
