TS4997IQT

Overview

The TS4997IQT is a stereo audio amplifier integrated circuit manufactured by STMicroelectronics. It operates within a supply voltage range of 2.7 V to 5.5 V and delivers 1 W of output power per channel into an 8-ohm load. The device utilizes Class AB topology and features differential inputs for improved noise immunity. It is housed in a compact 16-pin QFN package measuring 4x4 mm, designed for surface-mount assembly.

Feature Summary

• Stereo audio amplification with differential input capability
• Class AB operation for efficient power delivery
• Compact 16-pin QFN surface-mount packaging

Applications

• Portable multimedia devices
• Consumer electronics audio systems
• Embedded audio processing units

Procurement Notes

Verify the specific suffix 'IQT' against official STMicroelectronics documentation to confirm pinout and thermal characteristics. Ensure compatibility with the intended PCB footprint and soldering profile. Confirm RoHS compliance status through current datasheets as regulatory requirements may evolve over time.

Selection Notes

Select this component when a dual-channel solution is required within a limited board area. The differential input feature makes it suitable for noisy environments where single-ended inputs might introduce interference. Verify that the 2.7 V minimum supply voltage aligns with the system's battery or power rail specifications.
