ISL99201IRTCZ-TK

Audio Amplifiers Overview

The ISL99201IRTCZ-TK is a fully integrated, high-efficiency Class D mono audio amplifier designed for mobile phone applications. It delivers 1.5W of output power in an 8-TDFN (3x3 mm) package. The device features a micro-power shutdown mode with a minimal shutdown current of 200nA to maximize battery life. It operates as a filterless amplifier, reducing external component count and board space requirements while maintaining high audio performance.

Audio Amplifiers Feature Summary

• Fully integrated Class D mono amplifier architecture optimized for mobile devices
• Filterless design capability reduces external passive component requirements
• Micro-power shutdown mode ensures minimal current consumption during standby

Audio Amplifiers Applications

• Mobile phone audio systems
• Portable consumer electronics requiring compact audio solutions
• Battery-powered devices prioritizing power efficiency

Audio Amplifiers Procurement Notes

Verify the specific suffix 'TK' indicates tape-and-reel packaging when ordering. Confirm the manufacturer source is Renesas Electronics Corporation or authorized Intersil distributors. Ensure the 8-TDFN package dimensions match your PCB footprint requirements. Check for RoHS compliance status if required by your manufacturing standards.

Audio Amplifiers Selection Notes

Select this component for applications requiring a single-channel audio solution with minimal external components. The filterless operation simplifies design but requires careful layout to manage EMI. Consider the 1.5W output power limit against your speaker impedance and volume requirements. The low shutdown current makes it suitable for always-on or frequently powered-down portable devices.
