TPA6211A1TDGNRQ1 – TEXAS INSTRUMENTS

The TPA6211A1TDGNRQ1 is a Texas Instruments single-channel, Class D audio amplifier specifically designed for portable applications requiring high efficiency and low noise. This device operates from a 2.5V to 5.5V supply voltage range, making it ideal for battery-powered systems. It features a quiescent current of typically 1.7mA at 3V, contributing to extended battery life. The amplifier boasts a 1.2W output power into a 8Ω load at 5V, with a typical total harmonic distortion plus noise (THD+N) of less than 0.1% at 1kHz._x000D_

Packaged in a space-saving 6-pin WSON (WCSP-6) package (4mm x 3mm), the TPA6211A1TDGNRQ1 integrates a shutdown mode for further power saving, enabling designers to implement power-on/off sequences efficiently. Its inherent high efficiency minimizes heat dissipation, eliminating the need for bulky heat sinks in many applications. Common use cases include portable speakers, headphones amplifiers in mobile devices, and other battery-powered audio systems where small size, high efficiency, and low noise are paramount. The integrated thermal protection circuitry safeguards the device against potential over-temperature conditions, enhancing its reliability. Designers benefit from its ease of use, requiring minimal external components for operation.
