• Surface Mount Availability 20-Pin Thermal • Supply Range: 9.5 V - 18 V

SOIC PowerPAD™

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- Ω 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).

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). VCC 7 1 IN1 1 µF + 60 k COR – + – + OUT1 4 ×1 470 µF 2.

TPA1517 www.ti.com SLOS162D – MARCH 1997 – REVISED FEBRUARY 2007 APPLICATION INFORMATION (continued) The audio outputs are biased to a midrail voltage which is shown by the following equation: V V MID + CC 2 The audio inputs are always biased to 2.1 V when in mute or normal mode. Any dc offset between the input signal source and the input terminal is amplified and can seriously degrade the performance of the amplifier.

TPA1517 www.ti.com SLOS162D – MARCH 1997 – REVISED FEBRUARY 2007 APPLICATION INFORMATION (continued) Figure 25 is a reference schematic that provides TTL-level control of the M/SB terminal. A diode network is also included which helps reduce turn-on pop noises. The diodes serve to drain the charge out of the output coupling capacitors while the amplifier is in shutdown mode. When the M/SB voltage is in the normal operating range, the diodes have no effect on the ac performance of the system.

TPA1517 www.ti.com SLOS162D – MARCH 1997 – REVISED FEBRUARY 2007 APPLICATION INFORMATION (continued) COMPONENT SELECTION Some of the general concerns for selection of capacitors are: • Leakage currents on aluminum electrolytic capacitors • ESR (equivalent series resistance) • Temperature ratings LEAKAGE CURRENTS Leakage currents on most ceramic, polystyrene, and paper capacitors are negligible for this application. Leakage currents for aluminum electrolytic and tantalum tend to be higher.
