STA533WF13TR

Overview

The STA533WF13TR is a Class-AB audio amplifier manufactured by STMicroelectronics. It features an 18 V maximum supply voltage and a 3 A output current capability. The device utilizes a quad power half-bridge architecture to deliver 20 W of output power into an 8 ohm load with a total harmonic distortion plus noise of 10%. It operates within a temperature range of 0 °C to +70 °C and requires a minimum supply voltage of 5 V. The component is housed in a PowerSSO EP package and is supplied in a reel format.

Feature Summary

Quad power half-bridge topology for multi-channel audio amplification
Class-AB operation mode for audio signal processing
Integrated thermal protection mechanisms

Applications

Audio amplifier circuit design
