LM567C - Tone Decoder

Download the LM567C datasheet PDF. This datasheet also covers the LM567 variant, as both devices belong to the same tone decoder family and are provided as variant models within a single manufacturer datasheet.

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.

Key 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 2.
