The AN7171NK and AN7176K are ICs for power ampli-

fication of 14W (13.2V, 4Ω) output. It can provide stereo

operation since two BTL amplifiers are incorporated in a

chip. It incorporates various protective circuits, thus pro-

viding high reliability. The circuits can be turned on or off

with supply pins energized, because the stand-by circuit

is built-in.
