TS4990EIKJT

Overview

The TS4990EIKJT is a Class-AB mono audio power amplifier manufactured by STMicroelectronics. It delivers 1.2 W continuous RMS output power into an 8 Ω load at 5 V supply voltage. The device operates within a supply voltage range of 2.2 V to 5.5 V and features a gain-bandwidth product of 1.5 MHz. Total Harmonic Distortion plus Noise (THD+N) is specified at 0.2%. It utilizes a single-supply configuration with differential input type and consumes 3.7 mA of operating current. The component supports an active low standby mode for power reduction.

Feature Summary

• Class-AB topology delivering high-fidelity audio amplification
• Active low standby mode for efficient power management
• Differential input configuration for noise immunity
• Flip-chip package design for compact integration

Applications

• Speaker audio amplification
• Portable electronic devices requiring low-power audio solutions
• Battery-operated consumer electronics

Procurement Notes

Verify the specific suffix 'EIKJT' against official STMicroelectronics documentation to confirm the flip-chip 9-bump packaging variant. Ensure compatibility with the required 2.2 V to 5.5 V supply range and 8 Ω load impedance specifications before procurement. Cross-reference the datasheet revision date to validate technical parameters.

Selection Notes

Select this component for applications requiring a single-channel mono amplifier with Class-AB performance characteristics. It is suitable for designs needing a 1.2 W output capability at 5 V. Consider the flip-chip footprint constraints and the requirement for differential input signals when integrating into the circuit layout.
