TDA7465

Overview

The TDA7465 is a digitally controlled audio tone processor manufactured by STMicroelectronics. It functions as an audio matrix designed for signal mixing applications. The device supports two channels and utilizes an I2C interface for control. It operates within a supply voltage range of 7V to 10.2V and is rated for an ambient temperature range of -10°C to +85°C. The component is housed in a 42-SDIP package with a width of 15.24mm, intended for through-hole mounting.

Feature Summary

• Digitally controlled audio tone processing capabilities
• Supports signal mixing via integrated audio matrix
• I2C digital interface for configuration
• Two-channel audio processing architecture

Applications

• Signal mixing systems
• Audio tone processing circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm exact pinout and electrical characteristics. Confirm RoHS compliance status and end-of-life status prior to design finalization. Ensure the 42-SDIP through-hole footprint matches the target PCB layout constraints.

Selection Notes

Select this component when a dedicated hardware solution for analog audio tone shaping and mixing is required. The I2C interface allows for digital control of analog parameters. Verify that the 7V to 10.2V supply requirement aligns with the system power rails and that the operating temperature range meets environmental specifications.

Part Context

This part belongs to the category of Audio Special Purpose ICs. It serves as a discrete solution for audio signal conditioning, distinct from general-purpose microcontrollers or complex DSPs. It provides specific analog domain functionality managed by digital commands.

Replacement Considerations

Check for direct pin-to-pin replacements in the STMicroelectronics audio portfolio. Evaluate alternative audio tone processors with similar channel counts and I2C interfaces if the TDA7465 is unavailable.
