TS488IQT

Overview

The TS488IQT is a Class-AB stereo headphone amplifier manufactured by STMicroelectronics, housed in an 8-DFN (2x2 mm) package. It operates on a single supply voltage ranging from 2.2 V to 5.5 V and delivers up to 130 mW per channel into a 16 Ω load at 5 V with 0.1% THD+N. The device features a typical quiescent current of 2 mA and ultra-low standby consumption of 10 nA. Key electrical parameters include a gain-bandwidth product of 1.1 MHz, input offset voltage of 20 mV, and high crosstalk immunity of 102 dB at 1 kHz.

Feature Summary

• Integrated pop-and-click noise protection circuitry for clean audio transitions
• Externally controlled low-power standby mode reducing supply current significantly
• Built-in short-circuit protection to safeguard output stages during fault conditions

Applications

• Stereo headset driving applications
• Portable consumer electronics requiring low-voltage operation
• Battery-powered audio devices

Procurement Notes

Verify component authenticity through authorized channels as the TS488IQT is designated as Not Recommended for New Designs (NRND). Confirm RoHS compliance status and check for Product Change Notifications regarding packaging or manufacturing site updates before finalizing procurement plans.

Selection Notes

Select this component for designs requiring a compact stereo amplifier solution with minimal external passive components. Ensure the application supports the 2.2 V to 5.5 V supply range and utilizes the 8-DFN footprint. Consider the NRND status when planning long-term production lifecycles.

Part Context

This part belongs to the TS488 family of audio amplifiers designed for portable applications. It serves as a dual-channel solution for driving stereo loads, offering a balance between power output and current efficiency in a small form factor suitable for space-constrained mobile devices.
