TPA6120A2DWPG4

Audio Amplifiers Overview

The TPA6120A2DWPG4 is a high-fidelity stereo headphone amplifier integrated circuit manufactured by Texas Instruments. It utilizes a current-feedback Class-AB architecture to deliver high bandwidth and extremely low noise, achieving up to 128dB of dynamic range. The device operates on a single or dual power supply ranging from 10V to 30V (±5V to ±15V). It features differential inputs and provides short-circuit and thermal protection. Packaged in a 20-HSOIC with exposed pad, it supports loads such as 600 Ohms.

Audio Amplifiers Feature Summary

• Current-feedback AB amplifier architecture delivers high bandwidth and extremely low noise for high fidelity audio reproduction.
• Differential input configuration enhances signal integrity and common-mode rejection.
• Integrated short-circuit and thermal protection mechanisms ensure operational reliability under fault conditions.

Audio Amplifiers Applications

• High-fidelity headphone amplifiers
• Professional audio equipment
• Recording studio monitoring systems

Audio Amplifiers Procurement Notes

Verify the specific suffix G4 indicates RoHS compliance when sourcing this component. Confirm package availability as the DWPG4 variant may have different stocking levels compared to standard versions. Ensure the design accounts for the 20-HSOIC exposed pad thermal requirements during PCB layout. Cross-reference datasheet revisions to confirm pinout consistency before finalizing production orders.

Audio Amplifiers Selection Notes

Select this component for designs requiring high dynamic range and low distortion in stereo headphone applications. The current-feedback topology offers gain-independent frequency response across wide gain settings. Consider the 10V to 30V supply range compatibility with existing system power rails. Evaluate the 20-HSOIC package for thermal dissipation needs relative to the target load impedance.

Audio Amplifiers Part Context

This part belongs to the TPA6120A2 series of high-performance audio amplifiers. It serves as a replacement for costly discrete designs in professional audio gear. The device is designed to prioritize music quality over amplifier artifacts. Related evaluation tools include the TPA6120A2EVM for development purposes.

Audio Amplifiers Replacement Considerations

The TPA6120A2DWPR is a direct functional equivalent within the same series. Verify package compatibility between HSOIC variants if substituting. Check RoHS status differences between G4 and non-G4 suffixes for regulatory compliance.
