TPA1517
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 2 1 I IN1 is the audio input for channel 1.
SGND 4 2 I SGND is the input signal ground reference.
SVRR 5 3 SVRR is the midrail bypass.
OUT1 7, 8 4 O OUT1 is the audio output for channel 1.
PGND 9, 12 5 PGND is the power ground reference.
OUT2 13, 14 6 O OUT2 is the audio output for channel 2.

is the supply voltage input.
M/SB is the mute/standby mode enable. When held at less than 2 V, this signal enables the
M/SB 17 8 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.
IN2 19 9 I IN2 in the audio input for channel 2.
1, 10, GND/HS are the ground and heatsink connections. All GND/HS terminals are connected directly to
