TPA3255DDVR Description

Short technical summary and product information.

The Texas Instruments TPA3255DDVR is a high-performance, analog input Class-D audio amplifier designed for demanding audio applications. It offers significant power delivery, with up to 315W in stereo mode into a 4 Ohm load and up to 600W in mono mode into a 2 Ohm load, all while maintaining low total harmonic distortion plus noise (THD+N) of 0.006% at 1 kHz.

This amplifier operates from a wide power stage supply voltage range of 18V to 53.5V, with an analog supply voltage between 10.8V and 13.2V. It supports multiple configurations including stereo, mono, 2.1, and 4xSE, making it versatile for different system designs. The device features an advanced integrated feedback design with high-speed gate driver error correction, ensuring high fidelity audio reproduction.

Packaged in an HTSSOP (DDV) with dimensions of 14 mm x 8.1 mm, the TPA3255DDVR is designed for efficient operation, achieving up to 90% efficiency at a 4 Ohm load. It includes comprehensive self-protection features such as undervoltage, overtemperature, clipping, and short circuit protection with error reporting. The operating temperature range is from 0 to 70 °C.
