Dual BTL 14W Audio Power Amplifier Circuit
s 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 cir-
cuit ON/OFF with a charge mode to power supply pin.
s Features
• High output power (BTL 14W × 2)
• Stand-by circuit built-in
• Protection circuits built-in (temperature, overvoltage,
V_OUT– GND short, Load short, V_OUT–V_CC short)
• Low shock noise from power ON/OFF operation
• Fewer external parts
• Highly stable operation
