TS4990EIJT

Overview

The TS4990EIJT is a single-channel Class AB audio power amplifier manufactured by STMicroelectronics. It delivers 1.2W of output power into an 8Ω load with a supply voltage range of 2.2V to 5.5V. The device features a gain-bandwidth product of 1.5MHz and operates within a temperature range of -40°C to 85°C. It utilizes a flip-chip package with 9 bumps, measuring 3mm in length and 0.88mm in height.

Feature Summary

• Integrates active low standby mode for power management
• Designed to minimize external component count for compact layouts
• Supports direct connection to speakers without output coupling capacitors

Applications

• Portable mobile phones
• Tablets and laptops
• Automotive audio systems

Procurement Notes

Verify the specific suffix EIJT against official datasheets to confirm the flip-chip 9-bump package configuration. Ensure compatibility with the required 2.2V to 5.5V supply rails and 8Ω load impedance. Confirm that the operating temperature range meets the environmental requirements of the target application.

Selection Notes

Select this component for applications requiring high efficiency and minimal board space due to its integrated design. It is suitable for battery-powered devices where low quiescent current and standby modes are critical. Verify that the system architecture supports the single-channel topology and Class AB performance characteristics.
