The LM567 is general purpose tone decoders designed to provide a saturated transistor switch to ground when an input signal is present within the pass band. 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 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 Specification:- Parameters Min Max Units Supply Voltage Pin 9 V Power Dissipation 1100 mW V8 15 V V3 -10 V V3 VA 0.5 V Operating Temperature Range LM567CM, LM567CN 0 70 °C PDIP Package 260 °C SOIC Package 215 °C 220 °C Storage temperature range, Tstg -65 150 °C Related Document:- LM567 IC Data Sheet
