XR-567A - Precision Tone Decoder

Description

The XR-567A provides all the necessary circuitry for constructing a variety of tone detectors and frequency decoders.

Phase-locked loop circuit techniques are used to provide operation from 0.01 Hz tp 500 kHz.

Features

  • an input preamp, a high-current logic output, and programmable output delay. The XR-567A, available in an a-Pin DIL package, is designed to offer improved frequency accuracy and drift characteristics over the standard industry 567. These changes offer improved overall circuit performance, while reducing initial circuit adjustments.
