11 / 20 page TPA1517 6-W STEREO AUDIO POWER AMPLIFIER SLOS162B – MARCH 1997 – REVISED MARCH 2000 11 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 APPLICATION INFORMATION amplifier operation 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).

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. Figure 23. TPA1517 Minimum Configuration The following equation is used to relate gain in V/V to dB: G dB + 20 LOG GV V |
