Audio Amplifiers datasheet and documents for LM384N

LM384N

Audio Amplifiers Overview

The LM384N is a 5W audio power amplifier designed for consumer applications. It features a wide supply voltage range of 10V to 22V and delivers high peak current capability of 1.3A. The device incorporates internal thermal limiting and short-circuit protection. Quiescent output voltage automatically centers at one-half the supply voltage. Input signals are referenced to ground with high input impedance of 150kΩ. Voltage gain is fixed internally.

Audio Amplifiers Feature Summary

Integrated thermal limiting and short-circuit proof output stage
Ground-referenced input stage with high input impedance
Automatic self-centering of quiescent output voltage
Standard dual-in-line package with integrated heat sink pins

Audio Amplifiers Applications

TV sound systems
AM-FM radio receivers
Simple phonograph amplifiers
Intercoms and line drivers
Ultrasonic drivers

Audio Amplifiers Procurement Notes

Verify the manufacturer origin, as Texas Instruments acquired National Semiconductor. Confirm the specific ordering suffix (e.g., N or NOPB) matches the required lead frame material and compliance standards. Ensure the datasheet revision aligns with the design requirements. Check for RoHS compliance status if environmental regulations apply to the target market.

Audio Amplifiers Selection Notes

Select this component when higher power output than the LM380 is required. It serves as a direct upgrade path for designs needing increased wattage on higher supply voltages. Consider the standard DIP package for ease of use in standard PC layouts. Evaluate thermal management needs due to the copper lead frame construction.

Audio Amplifiers Part Context

The LM384N belongs to the LM38x series of audio power amplifiers. It is positioned above the LM380 in terms of power handling capabilities. The device maintains similar interface characteristics while offering increased output power. It is widely used in legacy and modern consumer audio electronics requiring robust performance.
