TPA3131D2RHBR Description

Short technical summary and product information.

The Texas Instruments TPA3131D2RHBR is an efficient Class-D audio amplifier designed for various audio applications. It supports a wide operating voltage range from 4.5 V to 26 V, making it versatile for different power requirements. The amplifier delivers 4 W stereo output into an 8-ohm load at 7.4 V and can also operate in mono mode for up to 8 W.

Featuring over 90% power efficiency and low idle loss, this amplifier can operate without a heatsink in many applications. It utilizes advanced modulation schemes and has a switching frequency up to 1.2 MHz. The device includes integrated self-protection circuits for overvoltage, undervoltage, overtemperature, DC-detect, and short circuits with error reporting.

The TPA3131D2RHBR comes in a 32-pin VQFN package suitable for surface mounting. Its design incorporates a feedback power stage architecture for high PSRR and offers differential and single-ended inputs. It supports stereo and mono modes with a single-filter mono configuration, reducing component count and simplifying designs.
