TPA6211A1DGNR – TEXAS INSTRUMENTS

The TPA6211A1DGNR is a Texas Instruments single-channel, Class-D audio amplifier optimized for portable applications requiring high efficiency and low distortion. It operates from a 2.5V to 5.5V supply voltage, making it suitable for battery-powered devices. The device features a built-in shutdown mode, minimizing power consumption in standby. Output power reaches 1W into a 4Ω load at 5V, with a typical THD+N of <1% at 1kHz. It utilizes a proprietary feedback architecture for improved stability and transient response._x000D_ _x000D_ Packaged in a space-saving 6-pin WSON (WCSP) package, the TPA6211A1DGNR simplifies PCB layout. Its integrated features, including a thermal shutdown mechanism and short-circuit protection, enhance robustness. Common applications include portable speakers, headphones amplifiers, and small form-factor audio devices. The amplifier's high efficiency translates to extended battery life in portable designs, while its low noise characteristics contribute to superior audio fidelity. Its compact package and ease of integration make it a compelling choice where board space is at a premium and high performance is critical. Note the absence of external components for basic operation, simplifying design complexity.
