AD8002D

AD8002D is a Class AB, mono with shutdown mode, bridge audio power amplifier. At 1KHz input with 5V supply voltage, the maximum output power is: 3W (4Ω load, THD·10%), 2W (4Ω load, THD<1%); total harmonic distortion plus noise within the audio range is less than 1% (<20Hz·20KHz). AD8002D features a simple application circuit requiring minimal external components to deliver high-quality output power. The 8002D output requires no external coupling capacitors, bootstrap capacitors, snubber networks, or feedback resistors. AD8002D adopts SOP package, making it particularly suitable for low-power, compact portable systems. The 8002D can enter shutdown mode via control input to reduce power consumption. The 8002D incorporates an internal thermal shutdown protection mechanism. The 8002D operates stably and is unity-gain stable. The amplifier voltage gain can be adjusted by configuring external resistors for convenient application.
