ICs for Audio Common Use AN7174K 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 circuit ON/OFF with a charge mode to power supply pin.
