TPA3007D1PWG4

Overview

The TPA3007D1PWG4 is a mono bridge-tied load (BTL) Class-D audio power amplifier manufactured by Texas Instruments. It delivers 6.5W of output power into an 8-ohm load with high efficiency exceeding 85% at 12V supply, eliminating the need for heat sinks. The device operates on a single voltage supply ranging from 8V to 18V and features a differential input stage for improved common mode rejection. Key specifications include a THD+N of less than 0.2% at 4W output. It is housed in a 24-TSSOP package and supports digital gain configuration via GAIN1 and GAIN0 pins.

Feature Summary

• High-efficiency Class-D architecture eliminates the requirement for external heat sinks
• Differential input stage provides enhanced common mode and power supply rejection
• Configurable digital gain settings allow flexible system integration
• Integrated depop circuitry reduces audible noise during power-up and shutdown

Applications

• Powered speaker systems
• Audio amplification modules
• Consumer electronics requiring efficient mono audio output

Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's current datasheet to confirm compliance with RoHS3 standards and lead-free material composition. Ensure the ordering part number matches the exact package type and thermal characteristics required for your design. Cross-reference the component marking with official documentation to prevent counterfeit substitution.

Selection Notes

Select this component for applications requiring a single-channel high-power solution without complex thermal management. The fixed gain options must align with the source signal levels. Verify that the 8V to 18V supply range meets the system power budget. Consider the 24-TSSOP footprint constraints during PCB layout planning.

Part Context

This component belongs to the TPA3007 family of audio amplifiers. It serves as a high-efficiency alternative to traditional linear amplifiers in mono audio applications. The device integrates protection features such as short-circuit and thermal shutdown to ensure reliable operation under varying load conditions.

Replacement Considerations

The TPA3007D1PWR is the standard non-RoHS-compliant version of this component. Verify if the RoHS3 compliant 'G4' suffix is strictly required for regulatory purposes. No other direct functional substitutes are documented in the provided data.
