te cDESCRIPTION
le uThe TS4900 is an audio power amplifier designed
so rodto provide the best price to power ratio while pre-
serving high audio quality.
- Ob te PAvailable in MiniSO8 & SO8 package, it is capable
) leof delivering up to 0.7W of continuous RMS ouput
t(s opower into an 8load @ 5V.
c bsTS4900 is also exhibiting an outstanding 0.1%
u Odistortion level (THD) from a 5V supply for a Pout
rod -of 200mW RMS.
P t(s)An externally controlled standby mode control re-
te cduces the supply current to less than 10nA. It also
le uincludes an internal thermal shutdown protection.
so rodThe unity-gain stable amplifier can be configured
b Pby external gain setting resistors.
