## Description

The Texas Instruments TPA3129D2DAP is an analog input Class-D audio amplifier designed for home audio applications. It offers multiple output configurations, including 2x15W into an 8Ω load at 15V. The device operates over a wide voltage range of 4.5V to 26V and features very low idle current, typically less than 23mA.

With power efficiency greater than 90%, the TPA3129D2DAP minimizes heat dissipation, often eliminating the need for a heatsink. It incorporates adaptive modulation schemes and smart amplifier drivers. The switching frequency ranges from 300kHz to 1.2MHz, with AM avoidance and master/slave synchronization capabilities. Integrated self-protection circuits include overvoltage, undervoltage, overtemperature, DC-detect, and short circuit protection with error reporting.

The TPA3129D2DAP is available in a 32-pin HTSSOP (DAP) thermally enhanced package, measuring 11mm x 8.1mm with an area of 89.1 mm². It supports parallel BTL mode and mono-channel mode, as well as single and dual power supply modes.
