te c DESCRIPTION

le u The TS4900 is an audio power amplifier designed

so rod to provide the best price to power ratio while pre-

serving high audio quality.

- Ob te P Available in MiniSO8 & SO8 package, it is capable

) le of delivering up to 0.7W of continuous RMS ouput

t(s o power into an 8Ω load @ 5V.

c bs TS4900 is also exhibiting an outstanding 0.1%

u O distortion level (THD) from a 5V supply for a Pout

rod - of 200mW RMS.

P t(s) An externally controlled standby mode control re-

te c duces the supply current to less than 10nA. It also

le u includes an internal thermal shutdown protection.

so rod The unity-gain stable amplifier can be configured

b P by external gain setting resistors.
