ISL99201IRTCZ-T

Audio Amplifiers Overview

The ISL99201IRTCZ-T is a fully integrated, high-efficiency Class-D mono audio amplifier manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 2.4 V to 5.5 V and delivers 1.4 W of continuous output power into an 8 Ω load with less than 1% THD+N from a 5 V supply. The device features differential inputs, a common mode rejection ratio (CMRR) of 60 dB, and total harmonic distortion plus noise of 0.09%. It is housed in an 8-TDFN (3x3 mm) package with a maximum height of 0.73 mm and supports an operating temperature range from -40 °C to +85 °C.

Audio Amplifiers Feature Summary

• Fully integrated Class-D architecture designed for high efficiency and minimal external component requirements.
• Supports differential input signals to enhance noise immunity and signal integrity.
• Includes built-in protection mechanisms such as short-circuit and thermal shutdown capabilities.

Audio Amplifiers Applications

• Portable audio devices requiring efficient mono amplification
• Battery-powered consumer electronics
• Small form-factor speaker systems

Audio Amplifiers Procurement Notes

Verify the specific suffix 'IRT CZ-T' against official Renesas documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with system voltage rails between 2.4 V and 5.5 V. Confirm that the 8-TDFN footprint matches the PCB design. Check for obsolescence status or lifecycle notices directly from the manufacturer before finalizing procurement plans.

Audio Amplifiers Selection Notes

Select this component when a compact, single-channel solution is required for low-voltage applications. It is suitable for designs prioritizing efficiency and simplicity over multi-channel capability. Ensure the application can accommodate differential input signaling. Verify that the 1.4 W output power meets the acoustic requirements of the target speaker load.

Audio Amplifiers Part Context

This part belongs to the ISL99201 family of Class-D audio amplifiers. It is often compared with variants like the ISL99201IRTAZ-TK, which shares similar electrical characteristics but may differ in packaging or reel configuration. The series is designed for portable audio markets where space and power efficiency are critical constraints.

Audio Amplifiers Replacement Considerations

Check for direct pin-compatible alternatives within the Renesas portfolio. Verify if other Class-D mono amplifiers meet the 1.4 W @ 8Ω specification at 5V. Ensure any substitute maintains the same TDFN-EP-8 footprint and thermal performance characteristics.
