TPA6041A4RHBR

Audio Amplifiers Overview

The TPA6041A4RHBR is a stereo audio power amplifier and DirectPath headphone amplifier manufactured by Texas Instruments. It features a fully differential architecture with high PSRR, designed for portable applications. The device integrates a 3.3-V LDO regulator and operates within a supply voltage range of 2.5 V to 3.6 V. It supports gain settings from 10 dB to 21 dB via external resistors and includes an active low enable pin. The component is housed in a 32-pin VQFN package (RHB) measuring 5 mm x 5 mm, suitable for space-constrained designs.

Audio Amplifiers Feature Summary

• Integrates a 3.3-V LDO regulator for simplified power management
• Supports both speaker output and DirectPath stereo headphone drive
• Features fully differential architecture for high power supply rejection ratio
• Includes active low enable control for power optimization

Audio Amplifiers Applications

• Portable media players
• Mobile phones
• Personal digital assistants

Audio Amplifiers Procurement Notes

Verify the specific suffix RHBR confirms the tape and reel packaging format. Ensure the order quantity aligns with standard reel sizes provided by Texas Instruments or authorized distributors. Confirm compliance with RoHS standards and lead times prior to finalizing procurement orders.

Audio Amplifiers Selection Notes

Select this component when a combined speaker amplifier and headphone driver is required in a single package. The integrated LDO reduces external component count compared to solutions requiring separate regulators. Consider the 32-pin VQFN footprint for PCB layout constraints and thermal performance requirements in compact devices.

Audio Amplifiers Part Context

This part belongs to the TPA604x series of audio amplifiers from Texas Instruments. It shares architectural similarities with the TPA6043A4 and TPA6045A4 but differs in specific integration levels and gain configurations. The series targets consumer electronics requiring high-quality audio output with minimal external circuitry.

Audio Amplifiers Replacement Considerations

The TPA6043A4RHBR is a documented alternative within the same family. Verify pin compatibility and electrical specifications before substitution. Other members of the TPA604x series may offer similar functionality but require validation of specific gain and regulator requirements.
