Description

The TS4851 is a low power audio amplifier that can drive either both a mono speaker or a stereo headset. To the speaker, it can deliver 400 mW
(typ.) of continuous RMS output power into an 8 load with a 1% THD+N value. To the headset driver, the amplifier can deliver 30 mW (typ.) per
channel of continuous average power into a stereo 32  bridged-tied load with 0.5% THD+N @ 3.3 V.

This TS4851 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.
