Overview
The ISL54000IRTZ-T is a Class AB stereo audio amplifier system manufactured by Renesas Electronics Corporation. It integrates two bridge-tied load (BTL) amplifiers in a single package, designed for operation from a +2.7V to +5.5V single power supply. The device delivers up to 941mW of continuous average power into an 8Ω BTL speaker load at 5V with 1% THD+N. It features low power shutdown, thermal overload protection, and click/pop suppression circuitry. The component is housed in a 20-lead 4x4 thin QFN package.
Feature Summary
- Integrates two Class AB bridge-tied load (BTL) amplifiers for driving stereo speakers
- Includes click and pop suppression circuitry to eliminate audible transients during source changes or shutdown transitions
- Features low power shutdown mode that reduces supply current significantly when disabled
- Provides thermal overload protection to prevent damage under excessive heat conditions
Applications
- Battery powered handheld equipment
- Cellular and mobile phones
- MP3 players and portable media devices
- Handheld games and toys
Procurement Notes
Verify the obsolete status of this component before design finalization. Confirm RoHS compliance and MSL classification requirements for your assembly process. Check for available replacement options as the datasheet indicates no recommended replacement. Ensure PCB layout supports the exposed thermal pad for optimal heat dissipation.
Selection Notes
Select this part for applications requiring integrated stereo amplification in a compact form factor. It is suitable for systems operating on single supplies between 2.7V and 5.5V. Consider the 20-lead TQFN package constraints for PCB space. Verify that the required output power matches the 8Ω load specifications provided in the electrical characteristics.
Part Context
This component belongs to the ISL54000/ISL54001/ISL54002 family of integrated audio amplifier systems. While the ISL54001 and ISL54002 variants include input multiplexing capabilities, the ISL54000 provides basic stereo amplification without mux functionality. All variants share the same package type and core amplifier architecture.
Replacement Considerations
The datasheet explicitly states 'NO RECOMMENDED REPLACEMENT'. Contact Technical Support for potential alternatives. No public substitute part numbers are confirmed.
