詳細說明
The TA8254BHQ is a 4-channel audio power amplifier that is designed for use in car audio systems. It has a maximum power output of 50W per channel at 4 ohms and 10% THD. The amplifier has a wide power supply voltage range of 6V to 18V, making it suitable for a variety of automotive applications. This amplifier features a built-in mute function, which can be activated by applying a logic signal to the standby pin. It also has a built-in protection circuit that safeguards against overcurrent, thermal overload, and short circuits. The TA8254BHQ utilizes a BTL (Bridge-Tied Load) configuration, which allows for higher output power with a lower supply voltage. This makes it an efficient choice for automotive audio systems where space and power constraints are a concern. Additionally, the amplifier has a low distortion and noise level, ensuring clear and crisp audio output. It also has a compact and lightweight design, making it easy to integrate into car audio systems.
