LA4461N-E

Audio Amplifiers Overview

The LA4461N-E is a single-channel Class AB audio amplifier integrated circuit manufactured by onsemi. Designed for bridged-tied load (BTL) configurations, it operates within a supply voltage range of 8V to 18V. The device delivers an output power of 20W into a 4Ω load and 12W into an 8Ω load at 14.4V with 10% THD+N. It features a 10-SIP package with an exposed pad for thermal management and supports through-hole mounting.

Audio Amplifiers Feature Summary

Audio Amplifiers Procurement Notes

Verify the specific suffix 'E' against the manufacturer's current datasheet to confirm compliance with RoHS directives and material declarations. Ensure the 10-SIP package dimensions match the target PCB footprint. Confirm that the operating temperature range meets the environmental requirements of the final assembly.

Audio Amplifiers Selection Notes

Select this component when a single-channel BTL solution is required for medium-power audio tasks. Compare the 20W output capability against system impedance needs. Evaluate the thermal performance provided by the SIP package relative to available heatsinking options in the enclosure design.

Audio Amplifiers Part Context
