TS4994EIJT

Overview

The TS4994EIJT is a mono Class AB audio power amplifier manufactured by STMicroelectronics. It delivers 1W of continuous RMS output power into an 8Ω load at a 5V supply voltage. The device operates within a supply voltage range of 2.2V to 5.5V and features differential inputs for improved noise immunity. It incorporates pop-and-click suppression, thermal protection, and standby functionality. The component is housed in a 9-pin FlipChip package and is rated for operation between -40°C and +85°C.

Feature Summary

Differential input configuration enhances signal integrity and noise rejection
Integrated pop-and-click suppression minimizes audible transients during power-up and power-down
Built-in thermal protection safeguards the device against overheating under fault conditions

Applications

Portable multimedia players
Mobile phones and smartphones
Personal digital assistants (PDAs)
MP3 players and portable media devices

Procurement Notes

Verify current lifecycle status as the TS4994EIJT may be obsolete or end-of-life. Confirm availability through authorized distributors or qualified alternative sources. Ensure compatibility with existing PCB footprints and design specifications before procurement. Check for valid RoHS compliance documentation if required for specific regulatory standards.

Selection Notes

Select this component for applications requiring a single-channel audio solution with low supply voltage operation. The differential input interface is suitable for systems where common-mode noise rejection is critical. Consider the 9-pin FlipChip package constraints for layout and thermal management. Evaluate power requirements against the 1W output capability into standard 8Ω loads.

Part Context

The TS4994 belongs to STMicroelectronics' TS49xx series of audio amplifiers designed for mobile consumer electronics. This series emphasizes high efficiency and compact packaging to support space-constrained portable devices. The EIJT suffix typically denotes the specific tape-and-reel packaging variant of the FlipChip package.
