TPA5051RSAT

Overview

The TPA5051RSAT is a digital audio signal processor from Texas Instruments, housed in a 16-QFN (4x4 mm) package with an exposed pad. It operates on a supply voltage of 3V to 3.6V and supports an ambient temperature range of -40°C to +85°C. The device features two channels and utilizes an I2C interface for control. Key specifications include integrated delay functionality and support for signal mixing applications. It is designed for surface-mount installation and is available in Tape & Reel, Cut Tape, and Bulk packaging formats.

Feature Summary

• Integrated digital audio signal processor with delay capabilities
• Dual-channel architecture supporting signal mixing functions
• I2C serial interface for configuration and control
• Compact 16-VQFN package with exposed thermal pad

Applications

• Signal mixing in audio processing systems
• Digital audio delay applications
• Embedded audio signal conditioning

Procurement Notes

Verify the specific ordering suffix 'SAT' against the manufacturer's official documentation to confirm exact packaging type and reel specifications. Ensure compatibility with I2C bus requirements and check for any moisture sensitivity level (MSL) handling precautions during storage and assembly. Confirm that the 16-QFN footprint matches the target PCB design guidelines.

Selection Notes

Select this component when a dual-channel digital audio processor with built-in delay and mixing functions is required. Ensure the system power supply remains within the 3V to 3.6V range. Verify that the host controller supports the necessary I2C communication protocol. Consider the 16-QFN package dimensions and thermal pad requirements for proper heat dissipation and mechanical mounting.

Part Context

The TPA5051RSAT belongs to the Texas Instruments audio signal processor family. It is distinct from other TI audio ICs by its specific combination of dual-channel processing, delay functionality, and I2C control interface. The RSAT suffix indicates a specific tape and reel variant of the standard TPA5051 device.

Replacement Considerations

Consult the official datasheet for direct pin-to-pin compatible alternatives. Verify that any substitute component maintains the same 16-QFN package outline and electrical characteristics, particularly the 3V-3.6V supply range and I2C interface compatibility.
