Overview
The TPA711DGNR is a Class-AB audio amplifier manufactured by Texas Instruments, housed in an 8-pin MSOP-PowerPad package. It delivers up to 700 mW of output power into an 8-ohm load with a total harmonic distortion plus noise of 1.3%. The device operates on a single supply voltage ranging from 2.5 V to 5.5 V and features a gain-bandwidth product of 1.4 MHz. It supports mono or stereo configurations, draws 700 uA of quiescent current, and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Class-AB topology for high-fidelity audio reproduction
- Integrated thermal and short-circuit protection mechanisms
- Low quiescent current consumption for battery efficiency
- Single-supply operation capability
Applications
- Portable audio players
- Mobile phones
- Personal media devices
Procurement Notes
Verify the specific suffix 'G' indicates RoHS compliance and green material status as per manufacturer documentation. Confirm the MSOP-PowerPad package variant matches the design-in requirements for thermal dissipation. Ensure the ordering part number aligns with the reel quantity specifications provided in the official datasheet to avoid packaging discrepancies during assembly.
Selection Notes
Select this component when a compact, low-power solution is required for driving small speakers or headphones. The MSOP-PowerPad package offers a balance between size and thermal performance compared to standard SOIC variants. Consider the 1.3% THD+N specification against application audio quality needs and verify that the 2.5V to 5.5V supply range fits the system power architecture.
Part Context
This part belongs to the TPA711 series of audio amplifiers designed for portable electronics. It serves as a cost-effective alternative to more complex digital amplifiers while providing analog fidelity. The series is characterized by its simplicity, requiring minimal external components for implementation in space-constrained mobile and multimedia applications.
Replacement Considerations
The TPA711DR is a pin-compatible SOIC-8 variant offering similar electrical characteristics but with a different physical footprint. Designers must evaluate thermal management differences between the PowerPad and standard SOIC packages when substituting.
