TS4871EIDT

Overview

The TS4871EIDT is a mono audio power amplifier manufactured by STMicroelectronics, designed for high-quality audio applications. It delivers 1 W of continuous RMS output power into an 8 Ω load at a 5 V supply voltage. The device operates within a supply voltage range of 2.5 V to 5.5 V and features ultra-low distortion with a THD+N of 0.15%. It incorporates near-zero pop and click performance, unity-gain stability, and an external standby mode that reduces supply current to less than 10 nA. The amplifier includes internal thermal shutdown protection and short-circuit protection, housed in an 8-SOIC surface-mount package.

Procurement Notes

Verify the specific suffix 'EIDT' against official STMicroelectronics documentation to confirm the exact tape-and-reel packaging configuration and temperature grade. Ensure compatibility with the 8-SOIC footprint and check for any RoHS compliance updates or lifecycle status changes directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a single-channel mono amplifier is required for low-voltage portable systems. It is suitable for designs needing minimal external components while maintaining high audio fidelity. Consider the 8-SOIC package constraints and verify that the 2.5 V to 5.5 V operating range aligns with the system's power supply architecture.
