Details
LA4263 is an audio power amplifier integrated circuit designed for use in consumer electronics applications. It is a monolithic audio amplifier that operates on a single-supply voltage and is capable of delivering up to 2.2W of output power into an 8Ω load with a 10% total harmonic distortion (THD) at 1kHz. The IC features a wide operating voltage range of 2.7V to 15V, making it suitable for battery-powered applications.LA4263 utilizes a Class AB amplifier topology, which offers a good balance between efficiency and audio fidelity. It also incorporates a built-in thermal shutdown protection circuit to prevent the IC from overheating under high-power operating conditions. Additionally, it includes a standby mode that helps reduce power consumption when the amplifier is not in use.The IC is housed in a small inline 9-pin SIP package, making it easy to integrate into compact audio systems. It features a simple application circuit that requires minimal external components, reducing the overall system cost and complexity. With its low cost, small form factor, and reliable performance, LA4263 is a popular choice for audio amplification in portable devices, such as smartphones, tablets, and Bluetooth speakers
