TDA7464

Overview

The TDA7464 is a dual-channel analog audio tone processor manufactured by STMicroelectronics. It integrates digital volume and balance control, surround sound processing, and tone controls within a single IC. The device operates on a supply voltage range of 7V to 10.2V and supports I²C interface communication for configuration. Designed for surface mount installation, it is housed in a 44-TQFP package measuring 10x10 mm. The component functions as an audio matrix processor suitable for signal mixing applications, operating within a temperature range of -10°C to 85°C.

Feature Summary

• Dual-channel audio tone processing with integrated digital volume and balance control
• I²C interface for digital configuration and control
• Supports surround sound and audio matrix signal mixing functions
• Housed in a 44-LQFP (44-TQFP) surface-mount package

Applications

• Signal mixing in consumer audio systems
• Surround sound processing setups
• Audio tone control circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm package type and temperature grade. Confirm availability status as older audio processor models may have limited stock or end-of-life status. Ensure the I²C address configuration matches the system design requirements before procurement.

Selection Notes

Select this component for applications requiring dual-channel analog audio processing with digital control capabilities. The 7V to 10.2V supply range suits standard automotive or home audio power rails. Consider the 44-TQFP footprint for PCB layout constraints. Verify that the -10°C to 85°C operating temperature range meets the environmental conditions of the target application.

Part Context

This part belongs to STMicroelectronics' portfolio of analog audio processors designed to enhance audio signal chains. These devices typically integrate multiple functions such as tone controls, balance, and volume management to reduce component count and cost in stereo and multichannel audio systems.

Replacement Considerations

Check for direct pin-to-pin replacements within the TDA74xx series. Verify compatibility of I²C command sets if substituting with other audio tone processors. Ensure the replacement package matches the 44-TQFP form factor.
