TDA7268

Overview

The TDA7268 is a dual-channel Class AB audio power amplifier manufactured by STMicroelectronics. It operates on a single supply voltage ranging from 4.5V to 18V and delivers up to 2W per channel into an 8-ohm load. The device utilizes a 16-PowerDIP package with through-hole mounting. Key electrical specifications include a maximum operating temperature of 70°C and compliance with RoHS3 standards.

Feature Summary

• Integrated protection mechanisms including pop-noise elimination, short-circuit protection, thermal overload protection, and standby functionality.

Applications

• Audio systems requiring low-power stereo amplification
• Portable electronic devices utilizing single-supply architectures

Procurement Notes

Verify component authenticity and datasheet revisions before integration. Confirm that the 16-PowerDIP footprint matches the target PCB layout. Check for end-of-life status or obsolescence notices from the manufacturer to ensure long-term supply chain stability.

Selection Notes

Select this component for designs requiring simple single-supply operation without external bootstrap components. Ensure the thermal management strategy accommodates the 70°C junction temperature limit. Verify that the 2W output capability meets the specific acoustic requirements of the application.

Part Context

This part belongs to the TDA72xx series of audio amplifiers from STMicroelectronics. These components are designed for straightforward implementation in consumer electronics where moderate power output and integrated protection features are prioritized over high-fidelity performance metrics.
