TDA7461ND

Audio Special Purpose Overview

The TDA7461ND is a two-channel analog audio signal processor manufactured by STMicroelectronics, designed for automotive applications. It operates on a supply voltage of 7.5V to 10V and supports I2C interface control. The device is housed in a 28-SOIC surface-mount package with an operating temperature range of -40°C to 85°C. Classified as an automotive-grade component, it functions as a dedicated audio signal processor within the specified electrical parameters.

Audio Special Purpose Feature Summary

• Two-channel audio signal processing capability
• I2C digital interface for configuration control
• Automotive-grade qualification for vehicle environments
• 28-SOIC surface-mount packaging

Audio Special Purpose Applications

• Automotive audio systems
• Car radio signal processing
• Vehicle infotainment front-end processing

Audio Special Purpose Procurement Notes

Verify the specific datasheet revision and availability status directly with STMicroelectronics or authorized distributors, as automotive components may have long-term supply commitments. Confirm that the 28-SO package matches the target PCB footprint and that I2C voltage levels are compatible with the host controller.

Audio Special Purpose Selection Notes

Select this component when a dedicated stereo analog audio processor with I2C control is required for automotive use. Ensure the design accommodates the 7.5V to 10V supply range and the thermal requirements of the 28-SOIC package within the -40°C to 85°C ambient temperature range.

Audio Special Purpose Part Context

This part belongs to STMicroelectronics' portfolio of specialized audio integrated circuits. It serves as a signal conditioning stage in automotive audio chains, distinct from power amplifiers like the TDA7561 or TDA7801, focusing on signal routing and processing rather than high-power output.

Audio Special Purpose Replacement Considerations

Check for direct pin-to-pin replacements within the TDA74xx series from STMicroelectronics. Verify compatibility with existing I2C addresses and register maps if substituting with other audio processors.
