TPA6040A4RHBR Description

Short technical summary and product information.

The TPA6040A4RHBR is a versatile stereo audio power amplifier and DirectPath headphone amplifier from Texas Instruments, housed in a thermally enhanced, space-saving 32-pin QFN package.

This amplifier is designed to drive 2 W per channel continuously into 4-ohm loads when supplied with 5 V. The headphone amplifier section can deliver a minimum of 85 mW at 1% THD+N from a 5-V supply. It features an internal 4-step gain control for the speaker amplifier, offering settings of 6, 10, 15.6, and 21.6 dB, along with 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) provide flexible power management. The device also includes output short-circuit and thermal protection. Its fully differential architecture and high PSRR offer excellent immunity to RF rectification, making it suitable for applications requiring robust noise rejection.

Applications for the TPA6040A4RHBR include notebook computers and portable DVD players, where space and power efficiency are critical.
