description
The TP A1517 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 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).

DESCRIPTION
IN1 is the audio input for channel 1.
SGND is the input signal ground reference.
SVRR is the midrail bypass mode enable.
OUT1 is the audio output for channel 1.
PGND is the power ground reference.
OUT2 is the audio output for channel 2.
VCC is the supply voltage input.
M/SB is the mute/standby mode enable. When held at less than 2 V , this signal enables the TP A1517
for standby operation. When held between 3.4 V and 8.8 V , this signal enables the TP A1517 for mute
operation. When held above 9.2 V, the TPA1517 operates normally.
IN2 in the audio input for channel 2.
GND/HS are the ground and heatsink connections. All GND/HS terminals are connected directly to
the mount pad for thermal-enhanced operation.

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.
