TPA6205A1DRBT

Overview

The TPA6205A1DRBT is a 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 supply voltage ranging from 2.5 V to 5.5 V and draws a typical quiescent current of 1.7 mA. It features analog input 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 architecture designed to reduce radio frequency rectification interference
• Integrated shutdown pin with logic threshold compatibility for low-power control
• High power supply rejection ratio to improve signal integrity in noisy environments

Applications

• Wireless handheld communication devices
• Personal digital assistants (PDAs)
• Mobile portable electronics requiring compact audio solutions

Procurement Notes

Verify the specific suffix DRBT against official datasheets to confirm the exact reel packaging configuration, as variations exist within the family. Ensure the source document explicitly lists this part number as active and compliant with RoHS standards before procurement. Cross-reference the manufacturer's latest product change notices to confirm material composition and assembly location consistency.

Selection Notes

Select this component when a fully differential Class-AB amplifier is required for driving 8-ohm speakers in space-constrained mobile designs. The 3mm x 3mm SON package minimizes PCB footprint compared to traditional packages. Consider the 1.7 mA quiescent current for battery life optimization and verify that the 2.5 V to 5.5 V supply range aligns with the system's power rails.

Part Context

This part belongs to the TPA6205A1 series of mono audio amplifiers. It shares core electrical specifications with variants like the TPA6205A1DRBR but differs in packaging or tape-and-reel specifications. The series is engineered for portable applications where small form factor and low power consumption are critical design constraints.

Replacement Considerations

The TPA6205A1DGNG4 is a verified alternative offering identical electrical performance in an MSOP-PowerPad-8 package. Verify pinout compatibility and thermal dissipation requirements when substituting between the SON and MSOP footprints.
