Description
The TS4997 is designed for top-class stereo
audio applications. Thanks to its compact and
power-dissipation efficient QFN16 package with
exposed pad, it suits a variety of applications.
With a BTL configuration, this audio power
amplifier is capable of delivering 1W per channel
of continuous RMS output power into an 8
Ω
load
@ 5V.
3D effects enhancement is programmed through
a two digital input pin interface that allows more
flexibility on each output audio sound channel.
Each output channel (left and right), also has its
own external controlled standby mode pin to
reduce the supply current to less than 10nA per
channel. The device also features an internal
thermal shutdown protection.
The gain of each channel can be configured by
external gain setting resistors.
