RT9114BGQV

Overview

The RT9114BGQV is a stereo channel Class-D audio power amplifier manufactured by Richtek USA Inc. It features an I2S digital input interface and delivers 20W per channel into 8-ohm BTL speaker loads. The device operates within a supply voltage range of 3V to 3.6V and supports an operating temperature range from -40°C to 85°C. Packaged in a 28-VFQFN (4x5) format with an exposed pad, it achieves over 90% power efficiency.

Feature Summary

High-efficiency Class-D architecture delivering over 90% power conversion
Integrated I2S digital input interface for direct digital audio connection
Stereo channel configuration providing dual independent audio outputs

Applications

Portable consumer electronics requiring high-fidelity audio output
Battery-powered devices utilizing I2S digital audio sources
Compact audio systems needing efficient power management

Procurement Notes

Verify the exact suffix 'BGQV' against the manufacturer's current datasheet to confirm pinout and thermal specifications. Confirm availability status as distribution channels may list obsolete or alternative revisions. Ensure the 28-VFQFN package footprint matches your PCB design constraints before finalizing procurement orders.

Selection Notes

Select this component when a digital I2S interface is required to eliminate external DACs. The high efficiency makes it suitable for battery-operated applications where power conservation is critical. Verify that the 3V to 3.6V supply range aligns with your system's power rails and that the 20W output capability meets the impedance requirements of the connected speakers.

Part Context

This part belongs to Richtek's audio amplifier portfolio, specifically designed for high-performance digital audio applications. It integrates Class-D amplification with digital control interfaces, distinguishing it from analog-input counterparts. The 28-VFQFN package allows for compact board layouts in space-constrained portable devices.
