GENERAL DESCRIPTION
FEATURES
The HAA9007 is a high efficiency filter-less Class-G audio● Built-In AGC technology power amplifier with Automatic Gain Control technology and
● 4 Constant Output Power levels Control: an adaptive high efficiency charge pump boost power supply. 1.2W ,1W ,0.8W ,0.6W@8Ω The device constantly monitors output power and dynamically
● Adaptive Charge Pump Power Supply adjust internal gain to prevent long time overstress across the
● Low Output Noise : 48μVrms @ gain=8V/V speaker.
● Built-in Class AB Receiver mode The adaptive charge pump structure activates automatically depending on the output signal. 技 It can deliver 1W (THD+N=1%) of continuous average power k to an 8Ω load by a lithium/Ion battery. T The AGC features multi-level constant output power, which can Improve sound quality and suppress the clipping noise. It 特 e also helps designer to select suitable output power which 源 rc match the speaker. The HAA9007 has a 48μVrms low output noise at gain=8V/V u to improve the signal to noise ratio (SNR).
