Description

The TS4998 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.

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.
