• Cassette recorders and players
• TV sets

Procurement Notes

Verify the specific manufacturer datasheet to confirm exact electrical parameters and pinout configurations. Ensure the selected package variant matches the required PCB footprint. Check current production status as older components may have limited availability or require alternative sourcing strategies.

Selection Notes

Select this component for low-power audio applications requiring simple implementation. The MiniDIP package facilitates through-hole mounting. Consider thermal management requirements based on the 1.6W output rating and ambient operating conditions within the target device enclosure.

Part Context

This part belongs to STMicroelectronics' legacy audio amplifier portfolio. It serves as a cost-effective solution for basic audio reproduction tasks in consumer electronics where high fidelity is not the primary design constraint.

Replacement Considerations

The TDA7231 and TDA7231A are listed as similar parts with identical 1.6W audio amplifier functionality. Verify pin compatibility before substitution.
