AF8002 3W Audio Power Amplifier with Shutdown Mode

General Description:

The AF8002 is a mono bridged audio power amplifier capable of delivering 3W of continuous average power into a 3W load with less than 10% THD when powered by a 5V power supply (Note 1). To conserve power in portable applications, the AF8002's micropower shutdown mode (IQ = 0.6μA, typ) is activated when VDD is applied to the SHUTDOWNpin. Boomer audio power amplifiers are designed specifically to provide high power, high fidelity audio output. They require few external components and operate on low supply voltages from 2.0V to 5.5V. Since the AF8002 does not require output coupling capacitors, bootstrap capacitors, or snubber networks, it is ideally suited for low-power portable systems that require minimum volume and weight.

Additional AF8002 features include thermal shutdown protection, unity-gain stability, and external gain set.
