Audio Amplifiers datasheet and documents for LM4890LD/NOPB

LM4890LD/NOPB

Audio Amplifiers Overview

The LM4890LD/NOPB is a Class-AB mono audio power amplifier manufactured by Texas Instruments. It delivers 1 W of output power into an 8 Ohm load with a total harmonic distortion plus noise of 0.1%. The device operates on a single supply voltage ranging from 2.2 V to 5.5 V and draws a typical operating current of 5 mA. It features an ultra-low current shutdown mode for battery conservation. The component is housed in a compact 10-WSON (3x4 mm) package, suitable for surface mount installation, and supports an operating temperature range from -40°C to +85°C.

Audio Amplifiers Feature Summary

Audio Amplifiers Procurement Notes

Verify the specific suffix LD against the manufacturer's official datasheet to confirm the 10-WSON package type and pinout configuration. Ensure the NOPB designation aligns with RoHS compliance requirements for your target market. Cross-reference the part number with the latest Texas Instruments documentation to confirm active status and any potential obsolescence notices before finalizing procurement plans.

Audio Amplifiers Selection Notes

Select this component when a single-channel, low-power audio solution is required for battery-operated equipment. The 10-WSON footprint offers a smaller alternative to VSSOP or SOIC packages for dense PCB layouts. Consider the 2.2 V minimum supply voltage when designing power rails for low-battery conditions. Verify thermal dissipation capabilities within the 10-WSON enclosure for continuous 1 W output operations.

Audio Amplifiers Part Context

The LM4890 series represents Texas Instruments' line of 1 Watt audio power amplifiers tailored for mobile electronics. This specific variant utilizes the LD suffix to denote the 10-WSON package, distinguishing it from other package options like VSSOP or SOIC within the same functional family. The NOPB suffix indicates lead-free and RoHS-compliant manufacturing standards.
