TDA7267A

Overview

The TDA7267A is a single-channel Class AB audio power amplifier manufactured by STMicroelectronics. It operates within a supply voltage range of 5V to 18V and delivers up to 3W of output power into an 8-ohm load. The device is housed in a 16-PowerDIP package with a pitch of 0.300 inches (7.62mm). It supports through-hole mounting and functions at ambient temperatures between 0°C and 70°C. Key integrated features include pop-noise elimination, short-circuit protection, thermal shutdown, and a standby mode for power management.

Feature Summary

• Integrated protection mechanisms including short-circuit and thermal shutdown capabilities
• Pop-noise elimination circuitry to prevent audible transients during power cycling
• Standby function designed to reduce power consumption when not in use

Applications

• Single-channel mono audio amplification systems
• Low-power consumer electronic audio devices
• Battery-operated audio equipment requiring efficient power management

Procurement Notes

Verify component authenticity and datasheet alignment as the TDA7267A is listed as obsolete. Confirm package integrity for the 16-PowerDIP format. Check RoHS3 compliance status. Ensure design-in compatibility with existing 5V to 18V supply rails. Review alternative sourcing options due to end-of-life status.

Selection Notes

Select this component for applications requiring a simple, single-channel Class AB solution with built-in protections. Suitable for designs needing pop-noise suppression without external components. Verify that the 3W output capability meets system requirements. Consider the 16-PowerDIP package constraints for PCB layout. Evaluate thermal performance within the specified operating temperature range.

Part Context

The TDA7267A belongs to the TDA7267 family of audio amplifiers from STMicroelectronics. It is designed for straightforward integration into audio circuits where moderate power output and reliability are prioritized. The device simplifies design by integrating essential protections and noise reduction features directly into the silicon, reducing the need for external support components.

Replacement Considerations
