TPA1517
SLOS162D – MARCH 1997 – REVISED FEBRUARY 2007
The TPA1517 is a stereo audio power amplifier designed to drive 4- Ω speakers at up to 6 W per channel.
Figure 23 is a schematic diagram of the minimum recommended configuration of the amplifier. Gain is internally
fixed at 20 dB (gain of 10 V/V).
A. When S1 is open, the TPA1517 operates normally. When this switch is closed, the device is in mute/standby mode.
B. When S2 is open, activating S1 places the TPA1517 in mute mode. When S2 is closed, activating S1 places the
TPA1517 in standby mode.
C. The terminal numbers are for the 20-pin NE package.

The following equation is used to relate gain in V/V to dB:
