LM2876TF/NOPB

Overview

The LM2876TF/NOPB is a high-performance Class-AB mono audio power amplifier from the Overture series by Texas Instruments. It delivers 40 W of output power into an 8 Ohm load with a total harmonic distortion plus noise of 0.06%. The device operates on a single supply voltage ranging from 20 V to 60 V and features a gain-bandwidth product of 8 MHz. It utilizes a TO-220 through-hole package, supports single or dual power supplies, and includes mute functionality for noise reduction during power transitions.

Feature Summary

• Integrated mute circuitry minimizes audible switching transients during power-up and power-down sequences.
• Class-AB topology provides high-fidelity audio reproduction with low distortion characteristics.
• Built-in thermal protection safeguards the device against overheating under fault conditions.

Applications

• High-fidelity stereo and mono audio amplification systems
• Professional audio equipment requiring low-distortion output
• Home theater and surround sound receiver channels

Procurement Notes

Verify the complete part number including the suffix /NOPB to ensure compliance with RoHS and REACH standards. Confirm that the TO-220 package variant matches your PCB footprint requirements. Cross-reference the manufacturer datasheet for specific pinout configurations and recommended operating conditions before finalizing procurement specifications.

Selection Notes

Select this component when a single-channel solution with 40 W output capability is required. Ensure the design accommodates the 20 V to 60 V supply range and the thermal management needs of the TO-220 package. Consider the 8 MHz gain-bandwidth product for frequency response requirements and verify compatibility with the intended speaker impedance loads.

Part Context

This component belongs to the LM2876 family within the Overture audio amplifier series. It serves as a robust alternative to legacy parts like the LM4700T, offering comparable performance in a standard through-hole package. The device is designed for applications demanding reliable high-power audio amplification with integrated protection features.

Replacement Considerations

The LM4700T is documented as a similar replacement option. Verify electrical parameter alignment and pin compatibility before substitution.
