TS4990 1W AUDIO POWER AMPLIFIER WITH ACTIVE LOW STANDBY MODE ADVANCE DATA s OPERATING FROM VCC = 2.2V to 5.5V s 1W OUTPUT POWER @ Vcc=5V, THD=1%, f=1kHz, with 8 Load PIN CONNECTIONS (top view) s ULTRA LOW CONSUMPTION IN STANDBY MODE (10nA) TS4990JT - FLIP CHIP s 62dB PSRR @ 217Hz @ Grounded mode s Zero POP & CLICK s ULTRA LOW DISTORTION (0.1%) s UNITY GAIN STABLE s AVAILABLE IN 9 BUMPS Flip Chip Package DESCRIPTION The TS4990 has been designed for demanding audio applications such as mobile phones and to minimize the number of external components. This Audio Power Amplifier is capable of delivering 1W of continuous RMS Ouput Power into an 8 load @ 5V. An externally controlled standby mode control 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.
