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.
z 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.
