Applications
The TAS5152DKDG4 serves as the output power stage in Class D audio amplifiers for home theater receivers, soundbars, and professional PA mixers where 125 W per channel drives 4-ohm or 8-ohm woofer and midrange speakers. It pairs with a TI PWM modulator to form a complete high-power digital amplifier solution, reducing overall component count. Automotive and commercial audio installations also use it where a 36 V supply bus is available and compact board size with high efficiency is required.

Frequently Asked Questions
How much output power can TAS5152DKDG4 deliver per channel, and what speaker impedances does it support?
The TAS5152DKDG4 delivers 125 W per channel with a combined 240 W total output power. It is designed to drive 4-ohm and 8-ohm speaker loads from a 0 V to 37 V supply, making it suitable for powering woofers and midrange drivers in home theater systems, soundbars, and professional PA speakers operating at standard 24 V or 36 V SMPS supply voltages.
What supply voltage range does TAS5152DKDG4 require, and can it run from a standard 24 V bench supply?
The TAS5152DKDG4 operates from a supply voltage of 0 V to 37 V, so a standard 24 V SMPS supply is fully within spec. Designers can also use 36 V supplies to extract maximum output power of 125 W per channel into a 4-ohm load. The wide voltage range provides flexibility across product lines without requiring separate power supply designs for different power levels.
Which Class D amplifier topology does TAS5152DKDG4 target, and what companion IC does Texas Instruments recommend?
The TAS5152DKDG4 is a pure power stage (output stage only) with 20 dB gain, designed to receive PWM drive signals from a separate modulator IC such as the TAS5086 or TAS5518 digital audio processor. This split architecture allows the modulator to handle signal processing and PWM generation while the TAS5152 focuses on delivering 125 W per channel with low THD, enabling scalable multi-channel amplifier platforms from 2 to 8 channels.
How does the TAS5152DKDG4 package help manage heat at 240 W combined output power?
The TAS5152DKDG4 is housed in a 36-lead PSOP package with an exposed thermal pad on the underside. The exposed pad bonds directly to the PCB copper pour and through-hole thermal vias, conducting heat away from the die to the board and an external heatsink. At 240 W combined output, designers typically target a thermal resistance below 1.5 °C/W from junction to board to keep junction temperature within the rated limit of 150 °C.
