TS4902

TS4902 300mW at 3.3V SUPPLY AUDIO POWER AMPLIFIER WITH STANDBY MODE ACTIVE LOW s OPERATING FROM VCC = 2.2V to 5.5V s 0.7W OUTPUT POWER @ Vcc=5V, THD=1%, f=1kHz, with an 8Ω load PIN CONNECTIONS (top view) s 0.3W OUTPUT POWER @ Vcc=3.3V, THD=1%, f=1kHz, with an 8Ω load s ULTRA LOW CONSUMPTION IN STANDBY MODE (10nA) s 77dB PSRR @ 217Hz from 5V to 2.2V s ULTRA LOW POP & CLICK s ULTRA LOW DISTORTION (0.1%) s UNITY GAIN STABLE s AVAILABLE IN MiniSO8 & SO8 DESCRIPTION The TS4902 is an audio power amplifier designed to provide the best price to power ratio while preserving high audio quality. Available in MiniSO8 & SO8 package, it is capable of delivering up to 0.7W of continuous RMS ouput power into an 8Ω 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 includes an internal thermal shutdown protection. The unity-gain stable amplifier can be configured by external gain setting resistors.
