ISL54001IRTZ-T

Overview

The ISL54001IRTZ-T is a Class AB integrated audio amplifier system featuring two bridge-tied load (BTL) channels. It operates on a single supply voltage ranging from +2.7V to +5.5V and delivers up to 941mW of continuous average power into an 8Ω load at 1% THD+N with a 5V supply. The device incorporates a 2:1 stereo input multiplexer for selecting between two audio sources, alongside low-power shutdown, thermal overload protection, and click/pop suppression circuitry.

Feature Summary

Integrated 2:1 stereo input multiplexer front-end for source selection
Built-in click and pop suppression to eliminate audible transients during switching
Low power shutdown mode significantly reduces quiescent current consumption
Thermal overload protection safeguards the device against overheating

Applications

Cellular and mobile phones
MP3 players and portable media devices
Handheld games and toys
PDAs and digital cameras

Procurement Notes

Verify component authenticity through authorized Renesas or Intersil distributors. Confirm RoHS compliance and Pb-free status by checking the datasheet revision and marking codes. Ensure the tape and reel specifications match TB347 requirements for surface mount assembly processes.

Selection Notes

Select this model when dual-channel stereo amplification with input switching is required in space-constrained designs. The 20-lead TQFN package supports efficient thermal dissipation via the exposed pad. Verify that the application requires TTL-compatible logic levels for the control pins and AC-coupled audio inputs.

Part Context

This component belongs to the ISL54000 family of integrated audio amplifier systems manufactured by Renesas Electronics (formerly Intersil). The family includes variants like the ISL54000 without multiplexing and the ISL54002 with mixing capabilities. All share the same 20 Ld 4x4 TQFN package and core amplifier architecture.
