LM567 Datasheet Tone Decoder

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM567/LM567C Tone Decoder May 1999 LM567/LM567C Tone Decoder General.

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 ponents are used to independently set center frequency, bandwidth and output delay.
