■ Overview

The AN7171NK and AN7176K are ICs for power amplification 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 providing high reliability. The circuits can be turned on or off with supply pins energized, because the stand-by circuit is built-in.

■ Features

• Two BTL 14W outputs built-in

• Stand-by circuit built-in

• Various protective circuits (for temperature, or against over-voltage, short-circuit between output and earth and between output and VCC, load short-circuit)

• Small shock noise at power ON/OFF

• Fewer external components required

• Good oscillation stability
