TDA7409DTR

Audio Special Purpose Overview

The TDA7409DTR is a two-channel audio signal processor manufactured by STMicroelectronics, designed for automotive applications. It operates within a supply voltage range of 7.5V to 10.5V and supports an ambient operating temperature from -40°C to 85°C. The device features an I2C interface for control and is housed in a 20-SOIC surface-mount package with a width of 7.50mm. Delivered in a tape and reel configuration, this component serves as a specialized integrated circuit for managing audio signals in vehicle infotainment systems.

Audio Special Purpose Feature Summary

• Two-channel audio signal processing capability
• I2C digital interface for system control
• Automotive-grade qualification for reliability
• 20-SOIC surface-mount package

Audio Special Purpose Applications

• Automotive audio systems
• Vehicle infotainment platforms
• Car speaker management

Audio Special Purpose Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and reel specifications. Ensure compatibility with existing I2C bus configurations and power supply rails ranging from 7.5V to 10.5V. Confirm that the 20-SOIC footprint matches the target PCB design constraints.

Audio Special Purpose Selection Notes

Select this component when a dedicated two-channel audio processor with I2C control is required for automotive environments. Consider the 20-SOIC package size for space-constrained designs. Verify that the operating temperature range of -40°C to 85°C meets the specific deployment conditions of the end application.

Audio Special Purpose Part Context

This part belongs to the TDA7407 family of audio processors from STMicroelectronics. While sharing similar functional characteristics such as dual-channel processing and automotive grading, the TDA7409DTR utilizes a 20-pin SOIC package compared to the 28-pin variant found in other family members. This distinction affects pinout compatibility and board layout requirements.

Audio Special Purpose Replacement Considerations

Check for direct pin-to-pin replacements within the same automotive audio processor series. Verify if alternative packages or updated revisions offer equivalent electrical performance and interface compatibility.
