Overview
The TPA6205A1DGNRG4 is a single-channel mono Class-AB audio amplifier manufactured by Texas Instruments. It delivers 1.25 W of output power into an 8-ohm load with a total harmonic distortion plus noise of 0.06%. The device operates on a single power supply ranging from 2.5 V to 5.5 V and draws a quiescent current of 1.7 mA. It features analog input and is housed in an MSOP-PowerPad-8 package. The component supports surface mount installation and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Fully differential architecture for improved noise rejection
- Low quiescent current consumption for battery efficiency
- Compact MSOP-PowerPad-8 package design
Applications
- Portable speaker systems
- Mobile phone audio outputs
- Personal media players
Procurement Notes
Verify the complete part number including the G4 suffix to ensure compliance with lead-free manufacturing standards. Confirm the specific package variant matches the required PCB footprint. Check official documentation for any recent product change notices that may affect pinout or electrical characteristics before finalizing procurement orders.
Selection Notes
Select this component when a low-power, single-channel solution is required for small form factor designs. The fully differential input helps maintain signal integrity in noisy environments. Ensure the application voltage stays within the 2.5 V to 5.5 V range to guarantee optimal performance and reliability without exceeding maximum ratings.
Part Context
This amplifier belongs to the TPA6205A1 series, designed specifically for portable audio applications. It integrates a robust Class-AB output stage capable of driving standard 8-ohm speakers efficiently. The series emphasizes high fidelity with minimal external components, making it suitable for compact consumer electronics where space and power constraints are critical design factors.
Replacement Considerations
TPA6205A1DRBT offers identical electrical specifications but utilizes a SON-8 package instead of MSOP-PowerPad-8. Designers must account for physical footprint differences during replacement. Other family members like TPA6203A1DGN share similar power levels but may differ in input configuration or distortion metrics.
