TDA7442D

Audio Special Purpose Overview

The TDA7442D 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 features a specification accuracy of 0.5dB and functions within an ambient temperature range of -10°C to 70°C. Packaged in a 28-SOIC surface-mount case with a 7.50mm width, it is supplied in tubes. This component serves as a digital solution for precise audio signal processing in standard consumer electronics environments.

Audio Special Purpose Feature Summary

• Two-channel architecture for stereo audio tone processing
• I2C digital interface for configuration and control
• 0.5dB specification accuracy for signal integrity
• Surface mount 28-SOIC package (7.50mm width)

Audio Special Purpose Applications

• Consumer audio equipment
• Stereo tone control systems

Audio Special Purpose Procurement Notes

Verify the specific revision level and manufacturing date code against current STMicroelectronics availability records. Confirm that the 28-SOIC tube packaging aligns with automated assembly requirements. Ensure the operating temperature range of -10°C to 70°C meets the target application's environmental constraints before finalizing procurement.

Audio Special Purpose Selection Notes

Select the TDA7442D when a dedicated two-channel digital tone processor with I2C control is required for consumer audio devices. Compare the 7V-10.2V supply requirement against system power rails. Verify that the -10°C lower temperature limit is sufficient for the intended deployment environment compared to wider industrial grade alternatives.

Audio Special Purpose Part Context

This component belongs to the family of STMicroelectronics audio special purpose integrated circuits. It shares functional similarities with other models like the TDA7318D and TDA7440D, which also offer two-channel tone processing capabilities. However, the TDA7442D is distinct in its specific supply voltage range and operating temperature specifications tailored for consumer-grade applications.

Audio Special Purpose Replacement Considerations

Check for direct pin-compatible substitutes within the TDA744x series. Verify if alternative packages or extended temperature variants are available from the manufacturer for updated production needs.
