Overview
The Texas Instruments TAS5182DCARG4 is a stereo digital amplifier power stage controller designed to drive two discrete bridge-tied-load (BTL) MOSFET output stages. It operates with a 3.3-V digital interface and accepts stereo PWM inputs from TAS50XX processors. The device supports up to 100 W per channel at 6 Ω, achieving efficiency greater than 95%. Key electrical parameters include a switching frequency of 1500 kHz, THD+N less than 0.15% typical at 100 W, and supply voltage ranges of 9 V to 12.6 V for gate drive and 3 V to 3.6 V for logic. It utilizes a 56-terminal TSSOP SMD package.

- Stereo H-Bridge Controller
- Glueless Interface to TAS50XX Digital Audio PWM Processors
- Built-in Fault Detection including Overcurrent, Overtemperature, and Undervoltage Protection
Applications
- AV Receivers
- High Power DVD Receivers
- Power Amplifiers
- Home Theater Systems
- Subwoofer Drivers
Procurement Notes
Verify the current production status of the TAS5182DCARG4 before design implementation. Official documentation indicates this specific ordering suffix may be classified as obsolete. Confirm availability through Texas Instruments or authorized distributors to ensure compliance with long-term supply requirements for new designs.
Selection Notes
Select this component when designing high-power digital audio systems requiring direct control of discrete MOSFET H-bridges. Ensure compatibility with TAS50XX series PWM modulators for glueless integration. Verify that the external MOSFET selection supports the required current limits and thermal dissipation characteristics for the target application environment.
Part Context
The TAS5182 belongs to the Texas Instruments PurePath digital audio solutions family. It functions as a power stage controller rather than a complete amplifier, necessitating external MOSFETs and passive components. This architecture allows for scalable power delivery in professional and consumer audio equipment while maintaining high efficiency and low distortion.

FAQ
How does the TAS5182 handle fault conditions?
The device provides overcurrent, overtemperature, and undervoltage protection. Upon detecting a fault, it drives the SHUTDOWN terminal low and forces all gate outputs low to protect the MOSFETs and speakers.
What is the interface type for digital audio input?
The TAS5182 features a 3.3-V digital interface designed for a glueless connection to Texas Instruments TAS50XX digital audio PWM processors.
