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.
