LM567/LM567C
Tone Decoder
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 indepen-
dently set center frequency, bandwidth and output delay.
Features
n 20 to 1 frequency range with an external resistor
n Logic compatible output with 100 mA current sinking
capability
n Bandwidth adjustable from 0 to 14%
