GK2171 ——

3W Audio Power Amplifier with Shutdown Mode

z General Description

--- The GK2171 is a mono bridged audio power amplifier capable of delivering 3W of

continuous average power into a 3Ωload with less than 10% THD when powered by a

5Vpower supply .

--- The GK2171 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.

--- The GK2171 features include thermal shutdown protection, unity-gain stability, and

extrnal gain set.
