GK2171 - CS2

GK2171 3W Audio Power Amplifier

--- 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 vol.

Features

include thermal shutdown protection, unity-gain stability, and extrnal gain set. z Key Specifications
