STA333BW13TR ST Audio Amplifier | POWERSSO-36EPD | 2x10W, 4-16Ω

Product Overview

The STA333BW13TR is a high-efficiency digital audio power amplifier from STMicroelectronics, designed for compact and high-performance audio systems. It integrates a digital audio processor and two independent BTL (Bridge-Tied Load) channels, delivering up to 2x10W output power into 8Ω loads with low distortion. The device operates from a single supply voltage ranging from 4.5V to 18V, making it suitable for battery-powered and line-powered applications. Its advanced EMI suppression and low quiescent current enable compliance with stringent EMC standards.
