TS489IST

Overview

The TS489IST is a Class-A mono audio power amplifier manufactured by STMicroelectronics, designed for high-quality audio applications. It delivers 1W of continuous RMS output power into an 8-ohm load at a 5V supply voltage. The device operates within a supply voltage range of 2.2V to 5.5V and features ultra-low distortion with a THD+N of 0.15%. It incorporates pop and click reduction circuitry and offers an externally controlled standby mode that reduces supply current to less than 10nA. The amplifier is unity-gain stable and housed in an 8-pin TSSOP package.

Feature Summary

Delivers 1W continuous RMS output power into an 8-ohm load at 5V supply
Features pop and click reduction circuitry for improved audio quality
Supports external standby control with ultra-low consumption below 10nA
Includes internal thermal shutdown protection

Applications

Mobile phones
Portable devices
High-quality audio systems

Procurement Notes

Verify the specific suffix 'IST' corresponds to the TSSOP-8 package configuration as documented in the official datasheet. Confirm RoHS compliance status through the manufacturer's latest documentation. Ensure the selected variant matches the required operating temperature range of -40°C to +85°C for your specific application environment.

Selection Notes

Select this component when a single-channel mono amplifier is required with high output power capability relative to its supply voltage. The TS489IST is suitable for designs needing low quiescent current in standby modes and minimal external component count due to its unity-gain stability. Consider the TSSOP-8 package constraints for PCB layout and thermal management requirements.

Part Context

The TS489IST belongs to the TS4890 series of audio power amplifiers from STMicroelectronics. This series is engineered to minimize external components while providing robust performance for mobile and portable electronics. The part integrates essential protections such as thermal shutdown and pop-click suppression, making it a complete solution for mono audio output stages.
