AN7164N
BTL 47W Audio Power Amplifier Circuit
s Overview
The AN7164N is an integrated circuit designed for 47W
(VCC = 26.4V, 8Ω) 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.
s Features
• High output power
• Low distortion, low noise
• Low shock noise from power ON/OFF operation
• Incorporates stand-by circuits
• Incorporates protection circuits
