TPA3156D2DADR Description

Short technical summary and product information.

The TPA3156D2DADR from Texas Instruments is an analog input Class-D audio amplifier designed for home audio, speaker, TV, and soundbar applications. It delivers 2 x 70W into a 4-Ohm load at 24V or 140W in mono-channel mode. The device operates over a wide voltage range of 4.5V to 26V and boasts very low idle current, less than 23mA, which helps extend battery life in portable audio systems.

 

With power efficiency greater than 90%, the TPA3156D2DADR minimizes heat dissipation. It supports multiple switching frequencies from 300kHz to 1.2MHz and includes features like AM avoidance and master/slave synchronization. The amplifier utilizes a feedback power-stage architecture with high PSRR to reduce power supply requirements. It is available in a 32-pin HTSSOP package suitable for surface mounting.

 

Integrated self-protection circuits for overvoltage, undervoltage, overtemperature, DC-detect, and short circuit with error reporting enhance reliability. The TPA3156D2DADR is pin-to-pin compatible with TPA3116D2 and TPA3126D2, facilitating upgrades.
