Overview
The TPA6204A1DRBRG4 is a single-channel mono Class-AB audio power amplifier manufactured by Texas Instruments. It delivers 1.7 W of output power into an 8-ohm load with a total harmonic distortion plus noise of 0.02%. The device operates on a single supply voltage ranging from 2.5 V to 5.5 V and draws a typical quiescent current of 4 mA. It features fully differential inputs and is housed in an 8-pin SON package. The component supports an operating temperature range from -40°C to +85°C.
Feature Summary
- Fully differential input architecture for improved noise rejection
- Class-AB topology delivering high-fidelity audio performance
- Low quiescent current consumption for battery efficiency
Applications
- Portable media players
- Mobile handsets
- Personal digital assistants
Procurement Notes
Verify the complete part number including the G4 suffix to ensure compliance with RoHS standards and lead-free specifications. Confirm the SON-8 package variant matches your PCB footprint requirements. Check the datasheet for moisture sensitivity level handling procedures during assembly. Ensure the design accommodates the specified thermal dissipation characteristics for the target application environment.
Selection Notes
Select this component when a compact, low-power mono amplifier is required for portable electronics. The fully differential input simplifies interface design with source components. Consider the 8-SON package for space-constrained layouts. Evaluate the 1.7 W output capability against the specific speaker impedance and volume requirements of the end product.
Part Context
This device belongs to the TPA6204A1 series of audio amplifiers from Texas Instruments. It is designed specifically for mobile and portable applications requiring high sound quality in a small form factor. The series emphasizes low power consumption while maintaining robust audio performance metrics suitable for consumer electronics.
Replacement Considerations
The TPA6204A1DRB is a related variant within the same family. Verify pin compatibility and electrical specifications before substitution. Cross-reference with other TI mono amplifiers if different power levels or packaging options are needed.
