Description

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 independently set center frequency, bandwidth and output delay.

Applications

•	Touch tone decoding
•	Precision oscillator
•	Frequency monitoring and control
•	Wide band FSK demodulation
•	Ultrasonic controls
•	Carrier current remote controls
•	Communications paging decoders

Features

•	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
•	Highly stable center frequency
•	Center frequency adjustable from 0.01 Hz to 500 kHz
