6-W STEREO AUDIO POWER AMPLIFIER

TPA1517

SLOS162D – MARCH 1997 – REVISED FEBRUARY 2007

FEATURES

• Thermal Protection

• TDA1517P Compatible • Fixed Gain: 20 dB

• High Power Outputs (6 W/Channel) • Mute and Standby Operation

• Surface Mount Availability 20-Pin Thermal • Supply Range: 9.5 V - 18 V

SOIC PowerPAD™

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- Ω 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 the 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).
