HAA9005 Datasheet | ChipSourceTek

Built-in AGC with Two Limited Output Power Levels Class-D Audio Amplifier General Description Features The HAA9005 is a high efficiency filter-less Class-D audio - Built-in AGC with Dual Output Power Levels power amplifier with Automatic Gain Control (AGC) Control:0.6W@8Ω, 4.2V or 0.85W@8Ω, 4.2V technology. The device constantly monitors output power - Excellent Output Noise : and dynamically adjusts internal gain to prevent long time 42μVrms @Gain=8V/V, A-weighted overstress across the speaker. - Improved PSRR : The AGC with two limited output power levels control helps -70d B@Speaker Mode(Gain=8V/V, A-weighted) designer to select suitable output power which match the speaker. The HAA9005 can deliver 0.6W or 0.85W continuous 技 k average power to an 8Ω load at 4.2V power supply. It Features high efficiency up to 88%, which helps extend 科 e battery life when playing audio. T The HAA9005 Features excellent output noise at gain=8V/V to improve the signal to noise ratio (SNR) in speaker mode. 特 e The HAA9005 is available in small 1.5mm X1.5mm FCQFN-9 源 urc package with 500μm pitch. - High Efficiency : 88% - Improved THD+N : 0.006%@ 0.5W, 8Ω, 1k Hz - Thermal and Short-circuit Protection with Auto Recovery - Built-in Pop-and-click Noise Suppression - Low RF Susceptibility - Single Wire Pulse Control - Available in 1.5mm X1.5mm FCQFN-9 Package Applications - Mobile Phones and Tablets - Portable Media Players C矽hip So Simplified Application Diagram TEL: +86-0755-27595155 27595165 FAX: +86-0755-27594792 WEB:Http://.Chip Source Tek.
