description
The TPA1517 is a stereo audio power amplifier that contains two identical amplifiers capable of delivering 6 W
per channel of continuous average power into a 4-
load at 10% THD+N or 5 W per channel at 1% THD+N.
The gain of each channel is fixed at 20 dB. The amplifier features a mute/standby function for power-sensitive
applications. The amplifier is available in Texas Instruments patented PowerPAD 20-pin surface-mount
thermally-enhanced package (DWP) that reduces board space and facilitates automated assembly while
maintaining exceptional thermal characteristics. It is also available in the 20-pin thermally enhanced DIP
package (NE).

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: These devices have been classified as Class 1 ESD sensitive products per MIL-PRF-38535 Method 3015.7. Appropriate precautions
should be taken to prevent serious damage to the device.
