TPA2000D2PWR

Overview

The TPA2000D2PWR is a stereo Class-D audio power amplifier from Texas Instruments, housed in a 24-pin TSSOP package. It delivers 2 W into 3-Ω speakers with THD+N below 0.4%. Operating on a 5-V supply, it features a modulation scheme that eliminates the need for an output filter. The device includes four internal gain settings ranging from 8 dB to 23.5 dB and operates within a temperature range of -40 °C to 85 °C.

Feature Summary

• Filterless operation enabled by a specialized modulation scheme that reduces switching current and system cost.
• Integrated depop circuitry prevents audible popping during power-up and shutdown transitions.
• Comprehensive protection mechanisms including thermal shutdown, over-current detection, and under-voltage lockout.
• Configurable gain via digital inputs allows optimization for various input signal levels.

Applications

• Battery-powered multimedia speakers
• Notebook PC integrated audio systems
• Powered speaker enclosures

Procurement Notes

Verify the specific ordering suffix 'R' corresponds to the taped and reeled packaging format required for automated assembly processes. Confirm that the TSSOP (PW) package dimensions align with the target PCB footprint and soldering profile specifications before finalizing procurement orders.

Selection Notes

Select this component when designing compact stereo audio systems requiring high efficiency without external output filters. Ensure the application utilizes a 5-V power rail and requires differential or single-ended analog inputs. Verify that the available gain settings meet the source impedance requirements of the preceding audio stage.

Part Context

This device belongs to Texas Instruments' third-generation 5-V Class-D amplifier family. It represents an evolution in low-power audio amplification by integrating advanced modulation techniques directly into the silicon. This integration significantly reduces the bill of materials compared to traditional Class-D designs that rely on discrete LC components.

Replacement Considerations

The TPA2000D2PWP serves as a direct pin-compatible alternative offering the same electrical performance in a different physical package configuration.
