■ Overview

The AN7174K is an integrated circuit for 14W (13.2V, 4Ω) output power amplifier circuit. Two BTL amplifiers are built-in on a single chip and stereo operation is possible. It is highly reliable due to protection circuits built-in. The built-in stand-by circuit makes it possible to switch the circuit ON/OFF with a charge mode to power supply pin.

■ Features

• High output power (BTL 14W × 2)

• Stand-by circuit built-in

• Protection circuits built-in (temperature, overvoltage, VOUT– GND short, Load short, VOUT–VCC short)

• Low shock noise from power ON/OFF operation

• Fewer external parts

• Highly stable operation
