ISL54001IRTZ

Overview

The ISL54001IRTZ is a dual-channel audio power amplifier manufactured by Intersil, now part of Renesas Electronics. It operates in Class AB topology to deliver 1.23W of output power per channel when driven by a 5V supply. The device is housed in a 20-lead TQFN package with exposed pad for enhanced thermal performance. It supports a single 5V operating voltage and functions within an industrial temperature range from -40°C to +85°C.

Feature Summary

• Dual-channel architecture providing independent amplification for stereo applications
• Class AB operation ensures high fidelity audio reproduction with low distortion
• Compact surface-mount packaging designed for efficient heat dissipation

Applications

• Logarithmic and exponential operation circuits
• Multiplication and division circuits
• Precision measurement systems

Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Review the latest datasheet for any manufacturing changes or obsolescence notices issued by Renesas Electronics.

Selection Notes

Select this component for designs requiring moderate power output in a compact form factor. Ensure the PCB layout accommodates the thermal requirements of the TQFN package. Verify that the system power supply remains stable at 5V to maintain optimal performance specifications.

Part Context

This part belongs to the Intersil audio amplifier family, which focuses on high-performance analog signal processing. Intersil was acquired by Renesas Electronics, integrating these products into their broader portfolio of mixed-signal solutions for consumer and industrial markets.

Replacement Considerations

Consult official Renesas documentation for qualified substitute part numbers. Cross-reference pinouts and electrical characteristics carefully before implementing any alternative components.
