TDA7297SA

Overview

The TDA7297SA is a dual bridge audio amplifier designed for TV and portable radio applications. It delivers 10W per channel into an 8-ohm load with a supply voltage range of 6.5V to 18V. The device operates in Class-AB topology, featuring a gain of 32 dB and total harmonic distortion plus noise of 0.1%. It utilizes a Multiwatt-15 through-hole package, supports single power supply input, and functions within a temperature range of 0°C to +70°C.

Feature Summary

Dual bridge architecture optimized for stereo audio output
Integrated thermal protection mechanisms
Short-circuit proof output stage design

Applications

Television sets
Portable radios
Automotive e-Call systems
Telematics units

Procurement Notes

Verify the specific suffix 'SA' against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications relative to the standard TDA7297. Ensure the ordering documentation explicitly references the STMicroelectronics part number to avoid confusion with generic equivalents or older revisions that may lack automotive-grade features.

Selection Notes

Select this component when a dual bridge configuration is required for low-voltage audio applications. It serves as a direct replacement for TDA7266B and TDA7266SA. Consider the 10W output capability and 8-ohm load matching for consumer electronics where space constraints favor the Multiwatt-15 package over larger alternatives.

Part Context

Part of the TDA7297 series, which includes variants like the TDA7297. The TDA7297SA variant is specifically noted for its suitability in automotive telematics and e-Call systems, distinguishing it from general-purpose audio amplifiers in the same family.

Replacement Considerations

Pin-to-pin compatible with TDA7297, TDA7266B, and TDA7266SA. Verify functional equivalence regarding output power and protection features before substitution.
