DESCRIPTION
The TS4902 is an audio power amplifier designed
to provide the best price to power ratio while pre-
serving high audio quality.
Available in MiniSO8 & SO8 package, it is capable
of delivering up to 0.7W of continuous RMS ouput
power into an 8
load @ 5V.
TS4902 is also exhibiting an outstanding 0.1%
distortion level (THD) from a 5V supply for a Pout
of 200mW RMS.
An externally controlled standby mode reduces
the supply current to less than 10nA. It also in-
cludes an internal thermal shutdown protection.
The unity-gain stable amplifier can be configured
by external gain setting resistors.
