The TPA6047A4 is a stereo audio power amplifier and DirectPath headphone amplifier from Texas Instruments, housed in a space-saving 32-pin VQFN package. This amplifier is designed for applications requiring high-quality audio output for both speakers and headphones.
The speaker amplifier section is capable of driving 2.1 W per channel continuously into 4-Ohm loads from a 5-V supply, with 1% THD+N. It features an internal 4-step gain control, offering selectable gains of 10, 12, 15.6, and 21.6 dB, minimizing the need for external components. The DirectPath headphone amplifier can deliver a minimum of 100 mW into 16-Ohm headphones with 10% THD+N from the same 5-V supply and eliminates the need for output capacitors.
This device also includes a 4.75-V low dropout regulator (LDO) for CODEC power. Independent shutdown controls for the speaker, headphone amplifier, and LDO allow for flexible power management. The TPA6047A4 utilizes a fully differential architecture, providing excellent power-supply and common-mode noise rejection, which is crucial for immunity to RF rectification. Its operating temperature range is -40°C to 85°C.
Applications for the TPA6047A4 include notebook computers and portable DVD players, where space and power efficiency are critical. The thermally enhanced package ensures reliable operation under demanding conditions.
