TDA7463D

Overview

The TDA7463D is a digitally controlled audio tone processor manufactured by STMicroelectronics, designed for low-voltage portable audio systems. It integrates volume and tone (bass and treble) control functions with an Automatic Level Control (ALC) feature adjustable via a dedicated pin. The device utilizes serial bus communication for function control and employs bipolar/cmos technology to achieve low distortion, low noise, and dc stepping capabilities. It operates within a supply voltage range of 1.8V to 3V and supports a two-channel configuration.

Feature Summary

• Digitally controlled bass and treble tone processing with integrated volume control
• Adjustable Automatic Level Control (ALC) function via dedicated pin
• Low voltage operation suitable for portable systems (1.8V ~ 3V)
• I2C serial bus interface for comprehensive function control

Applications

• Consumer audio equipment
• Portable audio systems
• Quality audio applications requiring low voltage supply

Procurement Notes

Verify the specific package type upon ordering, as source data indicates both tube and tray packaging options for this component. Confirm the operating temperature range and supply voltage specifications match the target application requirements before procurement. Check current availability status as distribution channels may vary.

Selection Notes

Select the TDA7463D for designs requiring digital tone control in low-voltage environments. Ensure the system supports I2C communication for configuration. The 16-SOIC surface-mount package is suitable for compact consumer electronics. Verify that the 1.8V to 3V supply range aligns with the power budget of the portable device.

Part Context

This component belongs to the family of digitally controlled audio processors from STMicroelectronics. It is specifically engineered for applications where space and power consumption are critical constraints. The integration of tone controls and ALC into a single chip simplifies the design of high-quality audio signal chains in portable devices.

Replacement Considerations

Consult official STMicroelectronics documentation for verified cross-reference part numbers. Ensure any substitute component matches the 16-SOIC package, I2C interface, and 1.8V-3V supply voltage range. Verify functional equivalence regarding tone control channels and ALC capabilities.
