TEXAS INSTRUMENTS  LM567CM/NOPB  Audio Codec, Tone Decoder, 0 °C, 70 °C


Image is for illustrative purposes only. Please refer to product description.

Product Overview

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


Audio; Communications & Networking
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.
