HAA9005
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
