TPA2016D2RTJT

Overview

The TPA2016D2RTJT is a stereo Class-D audio amplifier manufactured by Texas Instruments, housed in a 20-QFN (4x4 mm) package. It operates on a supply voltage range of 2.5 V to 5.5 V and delivers up to 2.8 W per channel into a 4-ohm load. The device features differential inputs, I²C control for volume and AGC, and includes short-circuit and thermal protection. It supports an operating temperature range from -40°C to 85°C.

Feature Summary

• Integrates digital automatic gain control (AGC) and programmable limiter via I²C interface
• Supports differential analog input with built-in DC bias circuitry
• Includes hardware shutdown and fault status monitoring capabilities

Applications

• Battery-powered portable audio terminals
• Smart voice nodes and IoT audio devices
• Educational sound effect demonstration platforms
• Small embedded speaker systems

Procurement Notes

Verify the specific suffix RTJT against official datasheets to confirm pinout and packaging details. Ensure compatibility with 3.3V or 5V logic levels for I²C communication. Confirm that the 20-QFN footprint matches the target PCB design. Check for moisture sensitivity level requirements during storage and handling.

Selection Notes

Select this component when low power consumption and high efficiency are required for stereo audio applications. The integrated I²C interface allows for dynamic gain adjustment without external components. Consider the 20-QFN package size for space-constrained designs. Verify that the 2.8W output per channel meets the acoustic requirements of the target speakers.

Part Context

This part belongs to the TPA2016 family of Class-D audio amplifiers designed for portable electronics. It offers a compact solution for stereo audio playback with minimal external components. The integration of digital signal processing features like AGC reduces the need for external DSPs, simplifying the system architecture.

Replacement Considerations

Check for direct pin-to-pin replacements within the TPA2016 series. Verify if alternative packages such as RTJR offer identical functionality. Ensure any substitute maintains the same I²C address and register map for software compatibility.
