　　DESCRIPTION The TS4890 （MiniSO8 & SO8） is an Audio Power Amplifier capable of delivering 1W of continuous RMS. ouput power into 8Ω load @ 5V. This Audio Amplifier is exhibiting 0.1% distortion level （THD） from a 5V supply for a Pout = 250mW RMS. An external standby mode control reduces the supply current to less than 10nA. An internal thermal shutdown protection is also provided. The TS4890 have been designed for high quality audio applications such as mobile phones and to minimize the number of external components. The unity-gain stable amplifier can be configured by external gain setting resistors.

　　OPERATING FROM VCC = 2.2V to 5.5V ■ 1W RAI L TO RAIL OUTPUT POWER @ Vcc=5V， THD=1%， f=1kHz， with 8Ω Load ■ ULTRA LOW CONSUMPTION IN STANDBY MODE （10nA） ■ 75dB PSRR @ 217Hz from 5 to 2.2V ■ POP & CLICK REDUCTION CIRCUITRY ■ ULTRA LOW DISTORTION （0.1%） ■ UNITY GAIN STABLE ■ AVAILABLE IN SO8， MiniSO8 & DFN8
