Panasonic AN7176K, AN7171NK, AN7171K Datasheet

ICs for Audio Common Use

■ 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
