TDA7465$

Overview

The TDA7465 is a digitally controlled audio tone processor manufactured by STMicroelectronics. It operates on a single supply voltage ranging from 7V to 10.2V and supports an operating temperature range of -10°C to +85°C (TA). The device features I2C interface control for digital volume, balance, and tone adjustments. It is housed in a 42-SDIP package with through-hole mounting. This component functions as an audio matrix processor designed for signal mixing applications.

Feature Summary

• Digitally controlled audio tone processing via I2C interface
• Supports stereo (2-channel) audio signal mixing
• Operates within a 7V to 10.2V supply voltage range
• Available in 42-SDIP through-hole package

Applications

• Signal mixing in audio systems
• Audio tone processing circuits
• Stereo audio channel management

Procurement Notes

The TDA7465 is listed as a discontinued product by the manufacturer. Availability is restricted, and current stock status should be verified directly with authorized distributors or suppliers before procurement planning. No new production units are expected.

Selection Notes

Select this component for designs requiring integrated I2C-controlled audio tone processing in a through-hole format. Ensure the system power supply remains between 7V and 10.2V. Verify that the 42-SDIP footprint fits the PCB layout constraints. Consider end-of-life status when designing for long-term production runs.

Part Context

This part belongs to the category of Audio Special Purpose ICs. It serves as an analog audio processor IC offering digitally controlled features suitable for stereo applications. It integrates functions typically found in separate tone and volume control stages into a single chip.

Replacement Considerations

As the TDA7465 is discontinued, no direct public substitute part numbers are confirmed in the provided documentation. Designers must evaluate alternative audio processors based on pin compatibility, I2C register maps, and electrical specifications.
