TDA7449D13TR

Audio Special Purpose Overview

The TDA7449D13TR is a two-channel digital volume control integrated circuit manufactured by STMicroelectronics. Designed for consumer audio applications, it operates on a single supply voltage ranging from 6V to 10.2V and functions within an ambient temperature range of 0°C to 70°C. The device utilizes an I2C interface for configuration and control. It is housed in a 20-SOIC surface-mount package with a width of 7.50mm. Key performance specifications include a dynamic range of 100dB, ensuring high-fidelity signal processing for stereo audio paths.

Audio Special Purpose Feature Summary

• Two-channel digital volume control with I2C interface
• Single supply operation between 6V and 10.2V
• 100dB dynamic range specification
• Surface mount 20-SOIC (7.50mm width) package

Audio Special Purpose Applications

• Consumer audio equipment
• Stereo audio signal processing

Audio Special Purpose Procurement Notes

Verify the component status as discontinued or obsolete through official STMicroelectronics channels before procurement planning. Confirm that the 20-SOIC package dimensions match the target PCB footprint. Ensure I2C bus compatibility with the host controller. Check for RoHS3 compliance documentation if required by specific regional regulations.

Audio Special Purpose Selection Notes

Select this component for designs requiring precise digital attenuation in stereo audio chains. The 6V to 10.2V supply range suits standard single-supply audio systems. The 100dB dynamic range supports high-quality audio reproduction. Consider the 20-SOIC package size for space-constrained consumer electronics layouts.

Audio Special Purpose Part Context

This part belongs to the TDA7449 family of digital volume controls. It shares functional similarities with other members like the TDA7448 series but offers a two-channel configuration optimized for stereo applications. The 'D13' suffix typically denotes the tape and reel packaging variant.
