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

鈩?/div>

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

鈩?/div>

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.
