IS31AP4066D-QFLS2-TR

Overview

The IS31AP4066D-QFLS2-TR is a stereo Class AB audio amplifier IC manufactured by Lumissil Microsystems. It features a bridge-tied-load (BTL) output configuration and operates within a supply voltage range of 2.7V to 5.5V. The device delivers an output power of 1.3W into a 4Ω load at 5V supply. It utilizes a 16-pin QFN package measuring 3x3mm, designed for low-voltage portable audio applications requiring high efficiency and minimal external components.

Feature Summary

Stereo Class AB amplification with bridge-tied-load topology
Operates on low supply voltages from 2.7V to 5.5V
Compact 16-pin QFN surface-mount packaging

Applications

Portable media players
Mobile phone audio systems
Bluetooth speakers

Procurement Notes

Verify the specific suffix -QFLS2-TR against the official Lumissil datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure compatibility with your PCB footprint for the 16-QFN package. Check for any recent product change notices or lifecycle status updates directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a compact stereo amplifier solution is needed for battery-powered devices operating between 2.7V and 5.5V. The 1.3W output capability suits 4Ω loads in space-constrained designs. Consider the thermal performance of the exposed pad QFN package for your specific enclosure constraints.

Part Context

This part belongs to the IS31AP series of audio amplifiers from Lumissil Microsystems. It complements other single-channel and multi-channel variants in the family, offering a balanced solution for stereo applications where board space and power efficiency are critical design parameters.

Replacement Considerations

Direct replacements may include other 1.3W stereo Class AB amplifiers in 16-QFN packages from manufacturers like TI or STMicroelectronics. Verify pin-to-pin compatibility and electrical specifications such as THD+N and standby current before substitution.
