TPA6043A4RHBR

Audio Amplifiers Overview

The TPA6043A4RHBR is a 2-W stereo audio power amplifier and DirectPath™ headphone amplifier manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and delivers up to 2.3 W of output power. The device features an integrated 3.3-V LDO regulator, active low enable control, and adjustable gain from 6 dB to 21.6 dB. It utilizes a fully differential architecture with high PSRR and is housed in a 32-VQFN package suitable for -40°C to +85°C operation.

Audio Amplifiers Feature Summary

• Integrates a 3.3-V LDO regulator for simplified power management
• Supports both speaker and headphone outputs via DirectPath technology
• Features fully differential architecture for improved noise immunity
• Includes active low enable pin for power control

Audio Amplifiers Applications

• Portable multimedia devices requiring stereo audio amplification
• Headphone amplifier circuits in consumer electronics
• Speaker driver applications in battery-powered systems

Audio Amplifiers Procurement Notes

Verify the specific suffix RHBR indicates the tape-and-reel packaging configuration. Confirm the operating temperature range matches your environmental requirements. Ensure the 32-VQFN footprint aligns with your PCB layout constraints. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.

Audio Amplifiers Selection Notes

Select this component when a combined speaker and headphone amplifier solution is required. The integrated LDO reduces external component count compared to discrete solutions. Consider the gain range if signal conditioning is needed before amplification. Verify thermal performance under maximum load conditions given the compact package size.

Audio Amplifiers Part Context

This part belongs to the TPA6043A4 family of stereo audio amplifiers. It shares functional similarities with the TPA6041A4 but may differ in specific electrical characteristics or packaging options. The TPA6043A4 series is designed for portable audio applications where space and power efficiency are critical constraints.

Audio Amplifiers Replacement Considerations

The TPA6041A4RHBR is a documented substitute within the same product family. Verify pinout compatibility and electrical parameter alignment before substitution. Check if the alternative variant offers different gain settings or regulatory compliance certifications.
