RT9118GQW

Overview

The RT9118GQW is a stereo Class D audio amplifier manufactured by Richtek Technology. It delivers 10W per channel into bridge-tied load (BTL) speakers. The device operates on a supply voltage range of 8V to 17V. It utilizes a 28-WQFN package with dimensions of 4x5 mm. The component supports surface mount technology and functions within an ambient temperature range of -40°C to 85°C.

Feature Summary

• High efficiency Class D architecture for stereo audio amplification
• Capable of driving bridge-tied load (BTL) speakers with 10W per channel output
• Operates within a wide supply voltage range from 8V to 17V

Applications

• Stereo speaker driver systems
• Bridge-tied load audio output stages
• High-efficiency audio amplification circuits

Procurement Notes

Verify the specific suffix GQW against the manufacturer's official datasheet to confirm pinout, thermal characteristics, and packaging details. Ensure compatibility with the intended BTL speaker configuration and supply voltage constraints before integration. Cross-reference the 28-WQFN footprint requirements with PCB design specifications.

Selection Notes

Select this component when a high-efficiency stereo amplifier is required for BTL speaker applications. The 10W per channel rating suits medium-power audio needs. Verify that the system power supply falls within the 8V to 17V operating range. Confirm that the 28-WQFN package size fits the available board space and thermal management strategy.

Part Context

This part belongs to the RT9118 family of Class D audio amplifiers. The GQW suffix denotes the specific package type and tape/reel packaging configuration. It is designed as a linear IC for audio signal processing and power amplification in consumer electronics.

Replacement Considerations

Consult official substitution lists for compatible stereo Class D amplifiers with similar power ratings and package footprints. Verify electrical parameters such as supply voltage range and output power match the original design requirements.
