1 / 27 page 1/27 s OPERATING FROM V CC = 3.0 V to 5.0 V s SPEAKER: Mono, THD+N @ 1 kHz is 1% Max @ 1 W into 8 Ω BTL s HEADSET: Stereo, THD+N @ 1 kHz is 0.5% Max. @ 85 mW into 32 Ω BTL s VOLUME CONTROL: 32-step digital volume control s OUTPUT MODE: Eight different selections s Ultra low pop-and-click s Low Shutdown Current (0.1 µA, typ.) s Thermal Shutdown Protection s FLIP-CHIP Package 18 X 300 µm Bumps DESCRIPTION The TS4855 is a complete low power audio amplifier solution targeted at mobile phones. It integrates, into an extremely compact flip-chip package, an audio amplifier, a speaker driver, and a headset driver. The Audio Power Amplifier can deliver 1.1 W (typ.) of continuous RMS output power into an 8 Ω speaker with a 1% THD+N value. To the headset driver, the amplifier can deliver 85 mW (typ.) per channel of continuous average power into stereo 32 Ω bridged-tied load with 0.5% THD+N @ 5 V. This device features a 32-step digital volume control and 8 different output selections. The digital volume and output modes are controlled through a three-digit SPI interface bus.
