XR-567A decoder equivalent, precision tone decoder.
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 accur.
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. The circuit also features an input pream.
