TDA7433D

Audio Special Purpose Overview

The TDA7433D is a two-channel audio tone processor manufactured by STMicroelectronics, designed for automotive-grade applications. It operates on a supply voltage range of 7V to 10.2V and supports an ambient operating temperature from -40°C to 85°C. The device features I2C interface control and is housed in a 20-SOIC surface-mount package with a 7.50mm width. This component functions specifically as an audio tone processor within the broader category of special-purpose audio integrated circuits.

Audio Special Purpose Feature Summary

• Two-channel audio tone processing capability
• I2C serial bus interface for control
• Automotive grade qualification (-40°C to 85°C)
• 20-SOIC surface mount package

Audio Special Purpose Applications

• Automotive audio systems
• Car radio tone processing
• General audio signal conditioning

Audio Special Purpose Procurement Notes

The TDA7433D is listed as a discontinued product. Verification of current availability through authorized distributors or alternative sourcing channels is required before procurement planning. Ensure compatibility with existing design constraints given its end-of-life status.

Audio Special Purpose Selection Notes

Select this component when a dedicated two-channel tone processor with I2C control is needed for automotive environments. Verify that the 7V-10.2V supply range matches the vehicle's electrical system. The 20-SOIC package requires appropriate PCB footprint consideration for surface mount assembly.

Audio Special Purpose Part Context

This part belongs to STMicroelectronics' portfolio of analog and digital audio processors. It serves as a specialized solution for audio signal manipulation, distinct from power amplifiers like the TDA7491HV or other tone controllers such as the TDA7439DS which may offer different band configurations.

Audio Special Purpose Replacement Considerations

As the TDA7433D is discontinued, engineers must evaluate pin-compatible or functionally equivalent alternatives from the same manufacturer or competitors. Review datasheets for matching channel count, interface protocols, and automotive temperature ratings.
