Audio Amplifiers datasheet and documents for LM4863MT/NOPB

LM4863MT/NOPB

Audio Amplifiers Overview

The LM4863MT/NOPB is a dual audio amplifier manufactured by Texas Instruments, designed for stereo applications. It integrates two Class-AB amplifiers capable of delivering 2.2W of output power per channel into an 8-ohm load. The device also includes a dedicated stereo headphone amplifier section. It operates within a supply voltage range of 2.7V to 5.5V and supports an operating temperature range from -40°C to +85°C. The component is housed in a TSSOP-20 package.

Audio Amplifiers Feature Summary

Integrates dual 2.2W audio amplifiers with a separate stereo headphone driver
Supports single-supply operation with low quiescent current
Includes integrated shutdown mode for power conservation

Audio Amplifiers Applications

Portable multimedia devices requiring stereo audio output
Desktop speakers and small audio systems
Headphone amplification circuits in consumer electronics

Audio Amplifiers Procurement Notes

Verify the specific suffix 'MT' against the manufacturer's official datasheet to confirm the tape-and-reel packaging configuration. Ensure the 'NOPB' designation aligns with current RoHS compliance requirements. Cross-reference the pinout diagram with your PCB layout to prevent installation errors due to package variations.

Audio Amplifiers Selection Notes

Select this component when a combined solution for speaker and headphone outputs is required in a compact form factor. It is suitable for designs needing high efficiency and low distortion in portable battery-powered applications. Consider the thermal performance of the TSSOP-20 package relative to the expected power dissipation in the final enclosure.

Audio Amplifiers Part Context

This part belongs to the LM4863 series of audio amplifiers from Texas Instruments. The series is characterized by its ability to drive both loudspeakers and headphones from a single chip, reducing bill-of-materials count. It is commonly used in mid-range consumer audio equipment where space and power efficiency are critical design constraints.
