TDA7461NDTR

Audio Special Purpose Overview

The TDA7461NDTR 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 10V and supports an ambient operating temperature from -40°C to 85°C. The device features an I2C interface for configuration and control. It is housed in a 28-SOIC surface-mount package with a width of 7.50mm, specifically packaged in a Tape & Reel format for automated assembly.

Audio Special Purpose Feature Summary

• Two-channel audio signal processing capability
• I2C digital interface for system control
• Automotive grade qualification (-40°C to 85°C)
• 28-SOIC surface mount package

Audio Special Purpose Applications

• Automotive audio systems
• Car infotainment units
• Vehicle sound processing modules

Audio Special Purpose Procurement Notes

Verify the 28-SOIC package variant against the 20-SOIC TDA7460ND to ensure pin compatibility. Confirm the Tape & Reel packaging matches production line requirements. Check current availability status as automotive components may have specific lifecycle constraints.

Audio Special Purpose Selection Notes

Select this component when a two-channel audio processor with I2C control is required for automotive environments. Ensure the power supply design accommodates the 7.5V to 10V input range. Compare thermal performance in the 28-SOIC package against alternative packages if heat dissipation is a critical design factor.

Audio Special Purpose Part Context

This part belongs to the TDA746x series of audio processors from STMicroelectronics. It shares functional similarities with the TDA7460ND but utilizes a different 28-pin package instead of the 20-pin version. Both are designed for automotive audio signal conditioning.

Audio Special Purpose Replacement Considerations

The TDA7460ND is a similar two-channel processor but uses a 20-SOIC package. Direct substitution requires verifying pinout compatibility between the 28-pin and 20-pin variants.
