TDA7403DTR

Audio Special Purpose Overview

The TDA7403DTR is a two-channel automotive-grade audio signal processor manufactured by STMicroelectronics. It operates within a supply voltage range of 7.5V to 10V and supports I2C interface communication for configuration. The device is housed in a 20-SOIC surface-mount package with dimensions of 0.295 inches (7.50mm) width. It is designed for operation across an ambient temperature range of -40°C to 80°C, ensuring reliability in automotive environments.

Audio Special Purpose Feature Summary

• Two-channel digital audio signal processing capability
• Automotive grade qualification for vehicle applications
• I2C bus interface for control and configuration
• 20-SOIC surface mount package

Audio Special Purpose Applications

• Automotive audio systems

Audio Special Purpose Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with STMicroelectronics or authorized distributors before procurement. Confirm that the 20-SOIC package variant matches the target PCB footprint requirements. Ensure the operating temperature range of -40°C to 80°C aligns with the intended automotive environment specifications.

Audio Special Purpose Selection Notes

Select this component when a dedicated two-channel audio processor with I2C control is required for automotive designs. Compare against other TDA74xx series devices if additional channels or different package constraints are needed. Verify power supply stability within the 7.5V to 10V range during vehicle cranking and alternator load dump conditions.

Audio Special Purpose Part Context

This part belongs to the TDA740x family of audio processors from STMicroelectronics, which are specifically engineered for automotive sound system integration. These components typically handle tone control, balance/fader adjustments, and input switching via digital interfaces.

Audio Special Purpose Replacement Considerations

Check for pin-compatible alternatives within the TDA740x series. Verify if upgraded versions offer extended temperature ranges or additional features while maintaining the 20-SOIC form factor.
