TDA7442

Audio Special Purpose Overview

The TDA7442 is a two-channel audio tone processor manufactured by STMicroelectronics, designed for consumer audio applications. It operates on a supply voltage range of 7V to 10.2V and supports I2C interface control. The device is housed in a 32-SDIP package with through-hole mounting, suitable for an operating temperature range of -10°C to 70°C. It features a specification accuracy of 0.5dB and is classified as an obsolete product.

Audio Special Purpose Feature Summary

• Two-channel stereo audio tone processing capability
• I2C digital interface for control configuration
• 32-SDIP (0.400 inch) through-hole package

Audio Special Purpose Applications

• Consumer audio equipment
• Stereo tone control systems

Audio Special Purpose Procurement Notes

Verify component status as the TDA7442 is listed as obsolete or end-of-life. Confirm availability through authorized distributors or secondary market sources. Ensure compatibility with existing 32-SDIP footprints and I2C bus requirements during replacement planning.

Audio Special Purpose Selection Notes

Select this component for legacy consumer audio designs requiring integrated tone control via I2C. Verify that the 7V to 10.2V supply range matches the system power architecture. Ensure the 32-SDIP package dimensions fit the mechanical constraints of the target enclosure.

Audio Special Purpose Part Context

This IC belongs to STMicroelectronics' portfolio of analog audio processors. These devices typically integrate volume, balance, and tone controls to simplify audio signal chains in stereo and multichannel applications, reducing external component counts.

Audio Special Purpose Replacement Considerations

As the TDA7442 is obsolete, verify pin-compatible alternatives within the same family or functionally equivalent tone processors. Check if ordering suffixes indicate specific tape-and-reel packaging versus tube formats, though functional equivalence remains primary.
