ISL54002IRTZ-T

Overview

The ISL54002IRTZ-T is a stereo integrated audio amplifier system manufactured by Renesas Electronics Corporation. It operates from a single +2.7V to +5.5V supply and features two Class AB bridge-tied load (BTL) amplifiers designed for driving 8Ω speakers. The device delivers up to 941mW of continuous average power per channel at 5V with 1% THD+N. It includes a 2:1 stereo input multiplexer and a mixer function, along with low power shutdown, thermal overload protection, and click/pop suppression circuitry.

Feature Summary

• Integrated 2:1 stereo input multiplexer allowing selection between two distinct audio sources
• Built-in capability to mix two stereo inputs simultaneously for combined audio output
• Click and pop suppression circuitry eliminates audible transients during source switching and shutdown transitions
• Low power shutdown mode significantly reduces quiescent current consumption

Applications

• Battery powered handheld equipment such as cellular and mobile phones
• Portable media players including MP3 and DVD players
• Handheld gaming devices and toys
• Personal digital assistants (PDAs) and cameras

Procurement Notes

Verify the component status carefully as this part may be obsolete or discontinued. Confirm that the tape and reel suffix matches your automated assembly requirements. Ensure compatibility with RoHS standards and check for any specific manufacturing changes documented in product change notices before finalizing procurement plans.

Selection Notes

Select this component when a compact solution is required for driving stereo 8Ω speakers from a single low-voltage supply. It is suitable for designs needing flexible audio routing via the internal multiplexer or simultaneous mixing of dual audio streams. Consider the 20-lead TQFN package constraints and thermal pad requirements for PCB layout optimization.

Part Context

This device belongs to the ISL54000 family of integrated audio amplifier systems. While the ISL54000 lacks input switching and the ISL54001 offers only multiplexing, the ISL54002 uniquely provides both a 2:1 stereo input mux and a mixer function. All variants share similar power ratings, protection features, and packaging within the 20 Ld 4x4 Thin QFN form factor.

Replacement Considerations

Public documentation indicates no recommended replacement parts are available for this obsolete component. Designers should consult technical support for potential alternatives or consider redesigning with currently supported audio amplifier families.
