Details
LA4902 is an integrated dual channel class AB audio amplifier designed for car audio applications. It is capable of delivering a maximum output power of 17W per channel into a 4Ω load with a THD+N of less than 10% at 1kHz. The amplifier operates on a supply voltage range of 8V to 18V and features a wide frequency response of 20Hz to 40kHz.The LA4902 is equipped with a built-in standby function that helps reduce power consumption when the amplifier is not in use. It also has a mute function that can be activated to quickly silence the audio output. The amplifier is protected against overcurrent, overtemperature, and output short-circuit conditions, ensuring reliability and longevity in the audio system.The amplifier comes in a compact 9-pin SIP package, making it easy to integrate into car audio systems with limited space. It requires minimal external components for operation and can be connected directly to the speakers with ease.
