TS4962MEIJT

Overview

The TS4962MEIJT is a single-channel Class-D audio power amplifier manufactured by STMicroelectronics. It operates within a supply voltage range of 2.4 V to 5.5 V and delivers up to 2.8 W into a 4 Ω load with 10% THD+N at 5 V, or 2.3 W with 1% THD+N. The device features a 9-ball flip-chip package (UFBGA/FCBGA) measuring approximately 3 mm x 3 mm with a height of 0.88 mm. It supports an operating temperature range from -40°C to 85°C and includes standby mode functionality.

Feature Summary

• Filterless differential Class-D BTL architecture eliminates external output filters
• Integrated pop-and-click reduction circuitry for low switching noise
• Active-low standby mode reduces current consumption significantly
• Adjustable gain controlled via two external resistors

Applications

• Mobile phones and portable devices
• Automotive audio systems
• General-purpose portable electronics

Procurement Notes

Verify the specific suffix MEIJT against the manufacturer's latest datasheet to confirm package type and electrical characteristics. Ensure compatibility with the intended PCB footprint for the 9-ball flip-chip configuration. Check for any product change notices regarding availability or pinout modifications before finalizing procurement plans.

Selection Notes

Select this component when filterless operation and high efficiency are required in space-constrained designs. The adjustable gain feature allows flexibility in system design. Consider the thermal performance and heat dissipation requirements associated with the small flip-chip package during layout.

Part Context

This part belongs to the TS4962I series of Class-D amplifiers designed for mobile and automotive applications. It offers higher audio power output compared to traditional Class-AB amplifiers while extending battery life. The series is characterized by its ability to drive speakers directly without additional filtering components.

Replacement Considerations

LM4675TL/NOPB is listed as a substitute option.
