TDA7468D

Audio Special Purpose Overview

The TDA7468D is a two-channel audio tone processor manufactured by STMicroelectronics, designed for consumer audio applications. It features an I2C interface for digital control and operates within a supply voltage range of 5V to 10V. The device supports ALC surround specifications and is housed in a 28-SOIC package with a width of 7.50mm. It functions as an audio tone processor with surface mount installation capabilities. The component is rated for an operating temperature range of 0°C to 70°C (TA).

Audio Special Purpose Feature Summary

• Two-channel audio tone processing capability
• I2C digital control interface
• Supports ALC surround specifications
• Operates on 5V to 10V supply voltage

Audio Special Purpose Applications

• Consumer audio systems

Audio Special Purpose Procurement Notes

Verify the tube packaging configuration against specific project requirements. Confirm that the 28-SOIC footprint matches the PCB layout. Ensure the I2C bus timing aligns with the controller's capabilities. Check for end-of-life status or discontinuation notices from the manufacturer before finalizing design-in decisions.

Audio Special Purpose Selection Notes

Select this component for designs requiring dedicated analog tone processing controlled via I2C. The 28-SOIC package suits surface-mount assembly processes. Verify that the 5V-10V supply range fits the system power architecture. Consider the 0°C to 70°C operating temperature range for environmental constraints.

Audio Special Purpose Part Context

This part belongs to the TDA7468 series of audio processors. It shares functional similarities with other members of the family but differs in packaging and suffix codes. The 'D' suffix typically denotes the tube package variant, distinguishing it from tape-and-reel options like the TDA7468TR.

Audio Special Purpose Replacement Considerations

Check for direct pin-compatible substitutes within the same series. Verify if alternative packages offer identical electrical characteristics. Confirm availability of equivalent components from other manufacturers if sourcing becomes difficult.
