TPA6041A4 www.ti.com SLOS542–AUGUST 2007 2-W STEREO AUDIO POWER AMPLIFIER WITH DirectPath™ STEREO HEADPHONE DRIVE AND REGULATOR 1 FEATURES DESCRIPTION 23• Microsoft™ Windows Vista™ Compliant • Fully Differential Architecture and High PSRR The TPA6041A4 is a stereo audio power amplifier Provide Excellent RF Rectification Immunity and DirectPath™ headphone amplifier in a thermally enhanced, space-saving, 32-pin QFN package. The • 2.1-W, 1% THD+N Into 4-Ω Speakers and speaker amplifier is capable of driving 2.1 W per 85-mW, 1% THD+N Into 16-Ω Headphones channel continuously into 4-Ω loads at 5 V. The From 5-V Supply headphone amplifier achieves a minimum of 85 mW • DirectPath™ Headphone Amplifier Eliminates at 1% THD+N from a 5-V supply. A built-in internal (1) Output Capacitors 4-step gain control for the speaker amplifier and a fixed –1.5 V/V gain for the headphone amplifier • Internal 4-Step Speaker Gain Control: 10, 12, minimizes external components needed. 15.6, 21.6 dB and Fixed –1.5-V/V Headphone Independent shutdown control and dedicated inputs • 3.3-V Low Dropout Regulator for CODEC for the speaker and headphone allow the TPA6041A4 • Independent Shutdown Controls for Speaker, to simultaneously drive both headphones and internal Headphone Amplifier, and Low Dropout speakers. Differential inputs to the speaker amplifiers Regulator (LDO) offer superior power-supply and common-mode noise • Output Short-Circuit and Thermal Protection rejection.
