I
Overview
The AN7164N is an integrated circuit designed for 47W
(V
CC
= 26.4V, 8
) output power amplifier. High power
output (BTL 47W), low distortion and low noise are real-
ized. High reliability is obtained due to same kinds of pro-
tectors built in. Furthermore, ON/OFF is enabled even if
power is supplied to power supply pin by stand-by circuit.
