Feature Description (continued)

8.3.3 Low Total Harmonic Distortion

Harmonic distortions to an audio signal are created by electronic components in a circuit. Total harmonic

distortion (THD) is a measure of harmonic distortions accumulated by a signal in an audio system. The TL97x

devices have a very low THD of 0.003% meaning that they will add little harmonic distortion when used in audio

signal applications.

8.3.4 Operating Voltage

The TL97x devices are fully specified and ensured for operation from 2.7 V to 12 V. In addition, many

specifications apply from –40°C to 125°C.

8.4 Device Functional Modes

The TL97x devices are powered on when the supply is connected. Each of these devices can be operated as a

single supply operational amplifier or dual supply amplifier depending on the application.
