Panasonic AN7174K Datasheet
ICs for Audio Common Use
■ 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,

short)
•
Low shock noise from power ON/OFF operation
•
Fewer external parts
•
Highly stable operation
