LM4892MM/NOPB

Audio Amplifiers Overview

The LM4892MM/NOPB is a single-channel Class-AB audio power amplifier manufactured by Texas Instruments. It delivers 1 Watt of output power into an 8-ohm load, operating within a supply voltage range of 2.2 V to 5.5 V. The device features a Total Harmonic Distortion plus Noise (THD+N) of 0.1% and draws a typical quiescent current of 5 mA. It is housed in an 8-pin VSSOP package and supports surface-mount installation. The operational temperature range spans from -40°C to +85°C.

Audio Amplifiers Feature Summary

• Integrated depop circuitry to minimize speaker pop noise during power transitions
• Built-in thermal protection to safeguard the device under overload conditions
• Shutdown pin functionality for effective power management and battery conservation

Audio Amplifiers Applications

• Portable media players
• Mobile phones
• Personal digital assistants

Audio Amplifiers Procurement Notes

Verify the specific suffix MM against the official datasheet to confirm the VSSOP-8 package variant. Ensure the NOPB designation aligns with current RoHS compliance requirements for your region. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and avoid counterfeit components.

Audio Amplifiers Selection Notes

Select this component when a mono Class-AB amplifier is required for low-voltage portable applications. It is suitable for designs needing integrated thermal protection and shutdown capabilities. Consider the VSSOP-8 footprint constraints and the 2.2V minimum supply voltage requirement during schematic design.

Audio Amplifiers Part Context

This part belongs to the LM489x series of audio amplifiers from Texas Instruments. It shares functional similarities with other members like the LM4890 and LM4893 but differs in specific package options and minor electrical characteristics. The series targets consumer electronics requiring high efficiency and compact form factors.

Audio Amplifiers Replacement Considerations

LM4892MX/NOPB offers the same electrical performance in an SOIC-8 package. LM4892M/NOPB provides equivalent specifications in a standard SOIC-8 tube packaging option.
