TPA2012D2YZHT

Overview

The TPA2012D2YZHT is a stereo Class-D audio power amplifier manufactured by Texas Instruments. It delivers 2.1 watts per channel into a 4-ohm load and 1.4 watts into an 8-ohm load at 5 volts supply voltage with 10% THD+N. The device operates on a single power supply ranging from 2.7 to 5.5 volts. It features a NanoFree package, low quiescent current of 6 mA, and integrated thermal shutdown protection.

Feature Summary

• Filterless output design eliminates external inductors and capacitors for simplified board layout
• High efficiency operation suitable for battery-powered portable devices
• Integrated thermal shutdown and over-current protection mechanisms

Applications

• Portable multimedia players
• Cell phones and smartphones
• Personal digital assistants

Procurement Notes

Verify the specific suffix YZHT against the manufacturer datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with the target PCB footprint and soldering profile. Confirm RoHS compliance status through official documentation before integration.

Selection Notes

Select this component for applications requiring high efficiency and minimal external components. It serves as a direct replacement for discontinued TS2012 units in most designs. Consider gain settings and input configuration requirements when designing the surrounding circuitry.

Part Context

This part belongs to the TPA2012 series of stereo Class-D amplifiers. It is designed specifically for portable consumer electronics where space and power consumption are critical constraints. The series offers a balance of performance and simplicity for mobile audio applications.

Replacement Considerations

The TS2012 is identified as a discontinued equivalent part. The TPA2012D2 provides similar functionality with potentially slightly lower power output but remains interchangeable for the majority of projects.
