LM4860M/NOPB

Audio Amplifiers Overview

The LM4860M/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 total harmonic distortion plus noise of 0.72%. The device operates on a single power supply ranging from 2.7 V to 5.5 V and draws a typical operating current of 7 mA. It is housed in a SOIC-Narrow-16 package and supports surface mount installation. The operational temperature range spans from -20°C to +85°C, making it suitable for various consumer electronics applications requiring analog input amplification.

Audio Amplifiers Feature Summary

• Class-AB topology provides high-fidelity audio amplification with low distortion characteristics.

Audio Amplifiers Applications

• Audio signal amplification in portable electronic devices
• Mono audio channel driving in consumer electronics

Audio Amplifiers Procurement Notes

Verify the manufacturer designation as Texas Instruments, as National Semiconductor was acquired. Confirm the specific suffix NOPB indicates lead-free and RoHS compliance. Ensure the package type matches the required SOIC-Narrow-16 footprint for PCB layout compatibility. Cross-reference the datasheet revision to ensure alignment with current manufacturing specifications.

Audio Amplifiers Selection Notes

Select this component when a single-channel mono amplifier is required with moderate power output capabilities. Consider the 2.7 V to 5.5 V supply voltage range for battery-operated systems. Evaluate the 7 mA quiescent current against system power budget constraints. Verify that the thermal performance within the specified operating temperature range meets the application's environmental requirements.

Audio Amplifiers Part Context

This part belongs to the LM4860 series of audio amplifiers. It is distinct from other models like the LM4861 or LM4864 which may offer different channel configurations or packaging options. The LM4860M/NOPB specifically denotes the mono variant in a narrow SOIC package. It serves as a dedicated solution for mono audio applications rather than stereo or multi-channel setups found in other family members.

Audio Amplifiers Replacement Considerations

LM4861M/NOPB offers similar power output but in an 8-SOIC package. LM4864M/NOPB provides differential output in an 8-SOIC package. LM4865MX/NOPB is a stereo option with comparable power ratings. Verify pinout compatibility before substituting these alternatives.
