SLOS162D – MARCH 1997 – REVISED FEBRUARY 2007
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.

IN1 is the audio input for channel 1.
SGND is the input signal ground reference.
SVRR is the midrail bypass.
OUT1 is the audio output for channel 1.
PGND is the power ground reference.
OUT2 is the audio output for channel 2.
V
CC
is the supply voltage input.
M/SB is the mute/standby mode enable. When held at less than 2 V, this signal enables the
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.
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.
