TS4871IST ST Audio Amplifier | 8-MINISO | 1.2W Output, 2.5V-5.5V Supply

Product Overview

The TS4871IST is a high-performance audio power amplifier from STMicroelectronics, designed for portable and low-power applications. It delivers up to 1.2W of output power into an 8Ω load with a 5V supply, while operating from a single 2.5V to 5.5V supply. Housed in the compact 8-MINISO package, it is ideal for space-constrained designs. The device features low quiescent current, high PSRR, and thermal shutdown protection, making it suitable for battery-powered audio systems.
