LM4860MX/NOPB

Audio Amplifiers Overview

The LM4860MX/NOPB is a single-channel mono Class-AB audio amplifier manufactured by Texas Instruments. It delivers an output power of 1.15 W into an 8 Ohm load with a THD+N of 0.72%. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V and draws a typical quiescent current of 7 mA. It accepts analog input signals and is housed in a 16-pin SOIC-Narrow package. The component supports surface mount installation and functions within a temperature range of -20°C to +85°C.

Audio Amplifiers Feature Summary

• Single-supply operation capability
• Analog input interface

Audio Amplifiers Applications

• Portable audio devices
• Personal entertainment systems
• Low-power audio amplification circuits

Audio Amplifiers Procurement Notes

Verify the manufacturer designation as Texas Instruments, which acquired National Semiconductor. Confirm the suffix NOPB indicates lead-free and RoHS compliance. Ensure the package type matches the required 16-pin SOIC-Narrow footprint for PCB layout compatibility. Cross-reference the specific ordering code against official distributor catalogs to ensure authenticity and correct revision level.

Audio Amplifiers Selection Notes

Select this component for applications requiring a single-channel mono amplifier with moderate power output. It is suitable for designs constrained by a single low-voltage power supply. Consider the 16-pin package size relative to available board space. Evaluate the thermal performance at the maximum operating temperature of +85°C to ensure adequate heat dissipation without additional cooling measures.

Audio Amplifiers Part Context

This part belongs to the LM4860 series of audio amplifiers. It represents a transition from National Semiconductor to Texas Instruments following the corporate acquisition. The NOPB suffix distinguishes it as an environmentally compliant version. It serves as a specialized solution for mono audio channels where stereo separation is not required.
