TPA3001D1PWPRG4

Overview

The TPA3001D1PWPRG4 is a single-channel mono Class-D audio power amplifier manufactured by Texas Instruments. It delivers 20 W of continuous output power into an 8-ohm load with 10% THD+N at an 18 V supply voltage. The device operates on a single power supply ranging from 8 V to 18 V and features a fixed gain of 36 dB. It utilizes a 24-pin HTSSOP package with a PowerPAD thermal pad for efficient heat dissipation, eliminating the need for external heatsinks in typical applications.

Feature Summary

• Filter-free design utilizing third-generation modulation technology to reduce electromagnetic interference with minimal passive components.
• Integrated protection mechanisms including short-circuit protection against output-to-ground, output-to-supply, and output-to-output faults.
• Low quiescent current consumption of 8 mA at 12 V supply, with shutdown mode drawing less than 1 mA.
• Built-in pop-and-click suppression circuitry to minimize audible noise during power-up and power-down sequences.

Applications

• Active speaker systems
• LCD monitors and televisions
• Hands-free automotive kits

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the presence of the 'G4' suffix indicating lead-free and RoHS compliance status. Ensure storage conditions adhere to moisture sensitivity level 2 requirements to prevent package damage during reflow soldering processes.

Selection Notes

Select this component for designs requiring high efficiency without external cooling solutions. The fixed 36 dB gain simplifies signal chain architecture by removing variable gain stages. Verify that the application load impedance remains above 3.6 ohms to ensure stable operation within the specified electrical limits.

Part Context

This part belongs to the TPA3001D1 series of high-power D-class amplifiers. It serves as a bridge-load topology solution optimized for single-supply operation. The PWPR suffix indicates a tape-and-reel packaging format suitable for automated surface-mount assembly processes.

Replacement Considerations

The TPA3001D1PWP is the non-reel version of the same functional device. Both share identical electrical characteristics and pinouts. Designers should verify package compatibility when transitioning between reel and tube formats.
