TPA6045A4C

The TPA6045A4C is a stereo audio power amplifier and DirectPath ™ headphone amplifier in a thermally enhanced, space-saving, 32-pin QFN package. The speaker amplifier is capable of driving 2.1 W per channel continuously into 4- Ω loads at 5 V. The headphone amplifier achieves a minimum of 85 mW at 1% THD+N from a 5-V supply. A built-in internal 4-step gain control for the speaker amplifier and a fixed 1.5 V/V gain for the headphone amplifier minimizes external components needed.

Features of the TPA6045A4C are:(1)Microsoft  Windows Vista  Compliant; (2)Fully Differential Architecture and High PSRR Provide Excellent RF Rectification Immunity; (3)2.1-W, 1% THD+N Into 4-  Speakers and 85-mW, 1% THD+N Into 16- ? Headphones From 5-V Supply; (4)DirectPath  Headphone Amplifier Eliminates Output Capacitors (1); (5)Internal 4-Step Speaker Gain Control: 10, 12, 15.6, 21.6 dB and Fixed 1.5-V/V Headphone; (6)3.3-V Low Dropout Regulator for CODEC; (7)Independent Shutdown Controls for Speaker,Headphone Amplifier, and Low Dropout Regulator (LDO); (8)Output Short-Circuit and Thermal Protection.

The absolute maximum ratings of the TPA6045A4C can be summarized as:(1)Operating free-air temperature range: 40 to 85 ° C; (2)Operating junction temperature range: 40 to 150 ° C; (3)Storage temperature range: 65 to 150 ° C.
