Texas Instruments TPA6010A4 Stereo Class-AB Audio Amplifier with Stereo Headphone Drive, Volume Control and Bass Boost TPA6010A4PWP

The TPA6010A4 is a stereo Class-AB audio power amplifier designed for applications requiring headphone drive and volume control. It is capable of delivering 2.7 W of continuous RMS output power into 3-ohm loads, with a total harmonic distortion plus noise (THD+N) of less than 0.22% when driving 1 W into 8-ohm speakers across its specified frequency range. The amplifier features an internal gain control that eliminates the need for external gain-setting resistors, with adjustable gain from -86 dB to 34 dB in BTL mode and -92 dB to 28 dB in SE mode. Key features include a bass boost function, DC volume control adjustable from -34 dB to 20 dB, and buffered docking station outputs. The device operates with low supply and shutdown currents, making it suitable for battery-powered applications. It is housed in a thermally enhanced 28-pin TSSOP PowerPAD package, which allows for effective thermal management in multilayer PCB designs. The TPA6010A4 is optimized for notebook PCs and includes a PC-beep input and depop circuitry to minimize noise during power-up and shutdown.
