TPA3156D2DAD Description

Short technical summary and product information.

The Texas Instruments TPA3156D2DAD is an efficient Class-D audio amplifier designed for home audio, TV, and soundbar applications. It delivers 70W per channel into a 4-ohm load at 24V supply, with a mono configuration capable of 140W.

 

This amplifier operates from a wide supply voltage range of 4.5V to 26V, offering flexibility for various power designs. It features a low idle current of less than 23mA, contributing to power efficiency. The device boasts over 90% power efficiency and supports adaptive modulation schemes based on output power.

 

Key electrical characteristics include a typical THD+N of 0.1% at 1kHz and an RDS(on) of 0.09 ohms. The switching frequency can be set between 300kHz and 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 TPA3156D2DAD is housed in a 32-pin HTSSOP (DAD) package with a surface mount termination style. Its thermally enhanced package and pin-to-pin compatibility with TPA3116D2 and TPA3126D2 make it a versatile choice for audio system designs.
