This document is the datasheet of STA335W, which introduces the features and characteristics of the product.
The STA335W is a 2‑channel high‑efficiency digital audio system that integrates digital audio processing, digital amplifier control, and a full‑flexible (FFX) power output stage. It delivers up to 20 W per channel, supports 96 kHz internal processing, 24‑bit resolution, and offers a wide range of selectable sample rates and digital gain settings.
The document details the pin‑out, absolute maximum ratings, recommended operating conditions, thermal data, and electrical specifications. It includes tables for supply voltage ranges, digital supply voltages, thermal shutdown temperatures, and other key parameters needed for design and integration.
