TPA2000D1PWRG4

Overview

The TPA2000D1PWRG4 is a 2-W mono bridge-tied-load (BTL) Class-D audio power amplifier from Texas Instruments. It operates on a single supply voltage ranging from 2.7 V to 5.5 V and delivers up to 2 W of continuous output power into a 4-Ω load with less than 1% total harmonic distortion plus noise (THD+N). The device utilizes an optimized modulation scheme that eliminates the need for external LC output filters, thereby reducing electromagnetic interference and system component count. Key electrical characteristics include a low shutdown current of 0.05 µA, a typical supply current of 4 mA without a filter, and a high power supply rejection ratio (PSRR) of -77 dB.

Feature Summary

• Filterless operation enabled by third-generation Class-D modulation technology
• Integrated depop circuitry to minimize turn-on and shutdown popping noises
• Configurable internal gain settings selectable via digital input pins
• Comprehensive protection mechanisms including short-circuit and thermal safeguards

Applications

• Portable battery-powered audio devices requiring extended run times
• Notebook personal computers and integrated speaker systems
• Powered multimedia speakers
• Automotive infotainment and sound systems

Procurement Notes

Verify the specific ordering suffix 'G4' against the manufacturer's latest documentation to confirm lead-free compliance and RoHS status. Ensure the package type matches the design requirements, as this part number corresponds to the TSSOP-16 variant. Cross-reference the active production status and recommended operating conditions before finalizing procurement plans.

Selection Notes

Select this amplifier for applications prioritizing high efficiency and minimal external component count. The absence of an output filter makes it suitable for space-constrained designs where EMI shielding must be minimized. Consider the fixed gain options when designing the input stage, as the input impedance varies significantly depending on the selected gain setting.

Part Context

This component belongs to the TPA2000D1 series of Class-D audio amplifiers. It represents Texas Instruments' third-generation technology designed specifically for high-efficiency audio reproduction. The series focuses on eliminating the bulky inductors typically required in traditional Class-D designs while maintaining high audio fidelity and low power consumption.

Replacement Considerations

Direct substitutes within the same family include the TPA2000D1PW and TPA2000D1GQCR. Verify pin compatibility and thermal performance when transitioning between the TSSOP and MicroStar Junior BGA packages.
