The Texas Instruments LM49450SQ is an active Class-D audio amplifier designed for stereo applications. It delivers up to 2.5W of output power per channel into a 4Ω load with a typical THD+N of 0.06% at 1kHz. The device also includes a dedicated ground-referenced headphone amplifier capable of delivering 36mW into 32Ω.
This amplifier features a filterless Class D operation with selectable spread spectrum mode to reduce EMI. It supports I2S compatible audio interface with sample rates up to 192kHz and includes TI's 3D enhancement technology. Control is managed via an I2C-compatible interface with 32-step digital volume control.
The LM49450SQ operates from a power stage supply voltage range of 2.7V to 5.5V and an analog supply voltage range of 2.7V to 5.5V. It is housed in a space-saving 32-pin WQFN package measuring 5mm x 5mm. Key features include output short circuit protection, thermal overload protection, click and pop suppression, and micro-power shutdown.
This amplifier is suitable for various audio applications requiring efficient power delivery and high-quality sound reproduction, such as mobile phones, tablets, notebooks, and soundbars.
