TS4985EIJT

Overview

The TS4985EIJT is a stereo audio power amplifier manufactured by STMicroelectronics. It operates within a supply voltage range of 2.2V to 5.5V and delivers 1.2W per channel into an 8-ohm load. The device utilizes a Class AB topology and features a 15-flipchip (UFBGA/FCBGA) surface-mount package. Key functional attributes include differential input capability, pop-and-click elimination, standby mode, and thermal protection. It supports an operating temperature range from -40°C to 85°C.

Feature Summary

• Stereo output configuration with differential input support
• Integrated pop-and-click elimination for noise reduction
• Thermal shutdown protection for operational safety

Applications

• Portable audio devices requiring low-voltage operation
• Mobile phone speaker amplification
• Personal digital assistants and handheld media players

Procurement Notes

Verify component status as the TS4985EIJT is listed as obsolete or discontinued. Confirm availability through secondary market channels or authorized distributors holding remaining stock. Ensure compatibility with existing PCB footprints if replacing active inventory. Check for RoHS3 compliance documentation in available datasheets.

Selection Notes

Select this component for applications requiring a compact stereo amplifier with minimal external components. The flipchip package suits space-constrained designs. Consider the 2.2V minimum supply voltage for battery-powered systems. Verify that the 1.2W output power meets the specific acoustic requirements of the target application.

Part Context

This part belongs to the TS4985 family of audio amplifiers. It shares core specifications with other variants in the series but differs in packaging and pinout configuration. The 15-flipchip format distinguishes it from QFN or SOIC alternatives within the same product line.
