Overview
The TPA2000D2PWG4 is a stereo Class-D audio power amplifier from Texas Instruments. It delivers 2 W into 3-Ω speakers with THD+N less than 0.4%. The device operates on a single 5-V supply, drawing 8 mA in no-filter mode and 1 µA in shutdown. It features four internal gain settings ranging from 8 dB to 23.5 dB. The amplifier utilizes a modulation scheme that eliminates the need for an output LC filter. It includes integrated depop circuitry and comprehensive protection against short circuits, thermal overload, and under-voltage conditions.
Feature Summary
- Filterless operation enabled by optimized modulation scheme
- Four selectable internal gain configurations via logic pins
- Integrated depop circuitry to minimize startup noise
- Comprehensive protection including thermal and over-current safeguards
Applications
- Battery-powered multimedia speakers
- Notebook PC internal audio systems
- Powered speaker enclosures
- Portable audio devices requiring low supply current
Procurement Notes
Verify the specific package variant (TSSOP or HTSSOP) required for your PCB footprint before ordering. Confirm that the G4 suffix indicates lead-free and RoHS compliance as per standard Texas Instruments manufacturing practices. Ensure the design accounts for the correct gain setting inputs to match the desired input impedance.
Selection Notes
Select this component for applications prioritizing system cost reduction through the elimination of external output filters. It is suitable for designs requiring high efficiency at 5 V operation. Consider the input impedance variations associated with different gain settings when designing the preceding audio stage coupling network.
Part Context
This device belongs to the third-generation 5-V Class-D amplifier family from Texas Instruments. It improves upon previous generations by offering lower supply current, reduced noise floor, and smaller packaging requirements. The technology focuses on maximizing efficiency while minimizing the external component count for stereo audio amplification.
Replacement Considerations
Direct functional replacements within the same generation include the TPA2000D2PW and TPA2000D2PWP. Verify pin compatibility and thermal dissipation ratings if substituting between the TSSOP and HTSSOP packages.
