LM567CM/NOPB Datasheet PDF - TI

The LM567CM/NOPB is a general purpose Tone Decoder 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 centre frequency of the decoder. External components are used to independently set centre frequency, bandwidth and output delay.

● 20 to 1 Frequency range with an external resistor

● Logic compatible output with 100mA current sinking capability

● Bandwidth adjustable from 0 to 14%

● High rejection of out of band signals and noise

● Immunity to false signals

● Highly stable centre frequency

● 0.01Hz to 500kHz Centre frequency adjustable

●This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
