LM1876T/NOPB

Overview

The LM1876T/NOPB is a dual-channel Class-AB audio power amplifier from the Overture series by Texas Instruments. It delivers 20W of output power into an 8-ohm load with a total harmonic distortion plus noise of 0.08%. The device operates within a supply voltage range of 20V to 64V and features a gain-bandwidth product of 7.5 MHz. It utilizes a TO-220 package for through-hole mounting, supporting a wide operating temperature range from -20°C to +85°C.

Feature Summary

• Integrated mute and standby modes for enhanced system control
• Internal circuitry provides overload protection against current limits and thermal shutdown
• Designed for stable operation with minimal external component requirements

Applications

• High-fidelity stereo audio amplification systems
• Professional audio equipment requiring low distortion
• Consumer electronics utilizing dual-channel power amplification

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official datasheets. Check for obsolescence notices as availability may be restricted. Ensure proper handling procedures are followed during installation.

Selection Notes

Evaluate suitability based on required channel count and power output specifications. Consider thermal management requirements due to the TO-220 package type. Verify compatibility with available supply voltages within the specified operational range. Assess integration complexity regarding external component minimization.

Part Context

This component belongs to the LM1876 family of audio amplifiers, specifically designed for high-performance applications. It serves as a dual-channel counterpart to single-channel variants like the LM1875, offering stereo capabilities while maintaining similar protection features and low-distortion characteristics typical of the Overture series.
