TPA3110D2PWP

Overview

The TPA3110D2PWP is a stereo Class-D audio power amplifier manufactured by Texas Instruments. It delivers 15W of output power per channel into an 8-ohm load, operating within a single supply voltage range of 8V to 26V. The device features a total harmonic distortion plus noise (THD+N) of 0.1% and a fixed gain of 36dB. It utilizes an analog input interface and operates with a typical quiescent current of 32mA. The component is housed in a 28-pin HTSSOP package with an exposed pad for thermal management, suitable for surface mount installation across a temperature range of -40°C to +85°C.

Feature Summary

• Filter-free operation eliminates the need for external output filters, reducing bill of materials and board space.
• Integrated SpeakerGuard technology provides comprehensive protection against short circuits, over-temperature conditions, and pop-and-click noises during power-up and shutdown sequences.

Applications

• Portable battery-powered audio devices
• Desktop multimedia speakers
• Active loudspeaker systems

Procurement Notes

Verify the specific suffix PWP to confirm the HTSSOP-28 tube packaging configuration. Ensure compatibility with the required 8V to 26V single-supply architecture. Confirm that the 36dB fixed gain aligns with the system's input signal levels. Validate thermal design requirements for the exposed pad to maintain performance within the specified -40°C to +85°C operating range.

Selection Notes

Select this component when a high-efficiency stereo solution is required without external filtering components. It is appropriate for designs needing up to 15W per channel at 8 ohms. Consider the fixed 36dB gain when designing the preceding analog stage. The HTSSOP package requires adequate copper area on the PCB for heat dissipation to ensure reliable operation under maximum load conditions.

Part Context

This part belongs to the TPA3110D2 series of filter-free Class-D amplifiers. It serves as a stereo variant within Texas Instruments' portfolio of efficient audio power solutions. The device is designed to replace traditional linear amplifiers in applications where efficiency and thermal management are critical constraints.

Replacement Considerations

The TPA3110D2PWPR is the tape-and-reel version of this component, offering identical electrical specifications but differing only in packaging format for automated assembly processes.
