TS4982IQT

Overview

The TS4982IQT is a stereo audio power amplifier manufactured by STMicroelectronics, housed in a 32-QFN package. It integrates a Class-AB stereo loudspeaker driver and a ground-referenced stereo headphone driver within a single device. The component operates on a supply voltage range of 4.5V to 5.5V, delivering up to 2W of output power. Key electrical characteristics include a gain of 3.5 dB and an operating current of 12 mA. It supports an independent standby mode for power management.

Feature Summary

Integrates both a stereo loudspeaker driver and a ground-referenced stereo headphone driver
Features an independent standby mode for efficient power management
Utilizes Class-AB topology for audio amplification

Applications

Stereo loudspeaker driving in portable electronic devices
Ground-referenced stereo headphone amplification
Battery-powered consumer electronics requiring integrated audio solutions

Procurement Notes

Verify the specific package variant and manufacturing date code upon ordering. Confirm that the supply voltage requirements align with the 4.5V to 5.5V operational range specified for this component. Ensure compatibility with the intended thermal dissipation design for the 32-QFN package during integration.

Selection Notes

Select this component when a single IC solution is required for both speaker and headphone outputs. It is suitable for applications needing Class-AB performance with low quiescent current. Consider the 32-QFN footprint for PCB layout constraints and verify thermal requirements for continuous operation at maximum power levels.

Part Context

The TS4982IQT belongs to the TS498x series of audio amplifiers from STMicroelectronics. This series focuses on providing integrated audio solutions for portable devices. The I suffix typically denotes industrial temperature grade specifications, ensuring reliable operation across a wide temperature range compared to commercial variants.
