The TPA6040A4 is a stereo audio power amplifier and DirectPath headphone amplifier from Texas Instruments, housed in a thermally enhanced, space-saving 32-pin VQFN package.
This amplifier is capable of driving 2 W per channel continuously into 4- loads from a 5-V supply, with a THD+N of 10%. The headphone amplifier can deliver a minimum of 85 mW at 1% THD+N from a 5-V supply. It incorporates an internal 4-step gain control for the speaker amplifier and a fixed -1.5 V/V gain for the headphone amplifier, minimizing the need for external components.
Independent shutdown controls for the speaker, headphone amplifier, and the integrated 4.75-V low dropout regulator (LDO) allow for simultaneous operation. The device offers output short-circuit and thermal protection. Its fully differential architecture and high PSRR provide excellent RF rectification immunity.
Applications for the TPA6040A4 include notebook computers and portable DVD players.
