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 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).

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

DESCRIPTION
I IN1 is the audio input for channel 1.
I SGND is the input signal ground reference.
SVRR is the midrail bypass.
O OUT1 is the audio output for channel 1.
PGND is the power ground reference.
O OUT2 is the audio output for channel 2.
I 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
I TPA1517 for standby operation. When held between 3.5 V and 8.2 V, this signal enables the
TPA1517 for mute operation. When held above 9.3 V, the TPA1517 operates normally.
I 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.
