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
@ 3.3V.
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.
