ای سی LM567 (آیسی general purpose tone decoders)

تخفیف ویژه

General 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.
Features
 20 to 1 frequency range with an external resistor
 Logic compatible output with 100 mA current sinkingcapability
 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
Applications
 Touch tone decoding
 Precision oscillator
 Frequency monitoring and control
 Wide band FSK demodulation
 Ultrasonic controls
 Carrier current remote controls
 Communications paging decoders
