TDA7464$

Overview

The TDA7464 is a dual-channel analog audio tone processor manufactured by STMicroelectronics. It integrates an I2C-controlled audio matrix for signal mixing and tone adjustment within a single chip. The device operates on a supply voltage ranging from 7V to 10.2V and supports an extended operating temperature range of -10°C to 85°C (TA). Packaged in a 44-TQFP surface-mount case measuring 10x10 mm, it provides dedicated hardware for stereo audio processing applications requiring precise control over audio parameters.

Feature Summary

Dual-channel architecture with integrated audio matrix for signal mixing
I2C interface for digital control of audio parameters
Operating temperature range of -10°C to 85°C (TA)
Supply voltage range of 7V to 10.2V

Applications

Stereo audio tone processing
Signal mixing in consumer audio systems
Audio matrix routing applications

Procurement Notes

Verify the specific package variant against the 44-TQFP (10x10) specification during sourcing. Confirm that the supply voltage requirements align with the 7V to 10.2V operational range. Ensure the design accommodates the -10°C to 85°C ambient temperature limits for reliable performance in the target environment.

Selection Notes

Select this component for designs requiring a dedicated dual-channel tone processor with I2C control capabilities. The 44-TQFP package is suitable for surface-mount assembly processes. Verify that the system power supply can maintain the required 7V to 10.2V range under all load conditions to ensure stable operation of the internal audio matrix.

Part Context

This component belongs to the category of Audio Special Purpose ICs. It functions specifically as an audio tone processor, distinct from general-purpose amplifiers or microcontrollers. The integration of an audio matrix allows for complex signal routing and mixing without external discrete components, simplifying the overall audio signal chain design.
