4 Summary

This app note has described the internal signal generators that are available on the TAx5x1x/TAx5x1x-Q1 family of audio devices, along with guidelines on configuring them. The SG1 generator can be used in applications where a single “beep” is used as an indication for some system event. Likewise, the SG2 generator at higher sampling rates can be used to generate chirp pulses outside the audible band and hence can be used in applications involving ultrasonic generation and detection.
