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 TS4855 can deliver 1.1 W (typ.) of continuous RMS output power into an 8 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  bridged-tied load with 0.5% THD+N @ 5 V.

This device TS4855 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.
