ICs for Audio Common Use
I
Overview
The AN7171NK and AN7176K are ICs for power ampli-
fication of 14W (13.2V, 4
) 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.

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 V
CC
, load short-circuit)
Small shock noise at power ON/OFF
Fewer external components required
Good oscillation stability
