TPA032D01DCAR

Overview

The TPA032D01DCAR is a monolithic Class-D mono audio amplifier by Texas Instruments, housed in a 48-pin PowerPAD TSSOP (DCA) package. It operates on an 8 V to 14 V supply and delivers up to 10 W continuous average power into a 4 Ω load at 0.5% THD+N from a 12 V source. The device features bridge-tied load configuration eliminating output coupling capacitors, low shutdown current of 20 µA, and integrated thermal and under-voltage protection.

Feature Summary

• Bridge-tied load architecture for high-efficiency single-channel audio amplification without external output capacitors
• Integrated charge pump and internal 5-V regulator for stable operation across varying supply voltages
• Active-low mute and shutdown control inputs for precise power management and battery conservation
• Dual open-drain fault status outputs indicating thermal or under-voltage lock-out conditions

Applications

• High-fidelity audio systems requiring efficient mono speaker driving
• Battery-powered portable audio equipment due to low standby current
• Automotive audio applications utilizing 12-V power architectures
• Home theater and multimedia speaker systems

Procurement Notes

Verify the DCA package designation matches the required 48-pin PowerPAD TSSOP footprint. Confirm the 'R' suffix indicates tape-and-reel packaging suitable for automated assembly. Ensure the design supports the specified 8 V to 14 V operating range and includes adequate thermal dissipation for the PowerPAD substrate.

Selection Notes

Select this component for designs prioritizing high output power efficiency in a single-channel configuration. The differential input structure minimizes distortion, while the extensive protection circuitry enhances reliability. Consider the thermal requirements of the PowerPAD package when designing the PCB layout for optimal heat dissipation.
