TPA2005D1DRBR

Overview

The TPA2005D1DRBR is a mono Class-D audio amplifier manufactured by Texas Instruments. It operates on a single power supply ranging from 2.5 V to 5.5 V and delivers up to 1.25 W of output power into an 8-ohm load. The device features a total harmonic distortion plus noise (THD+N) of 0.06%. It utilizes an 8-pin SON package with dimensions of 3x3 mm. The operational temperature range spans from -40°C to +85°C, and the quiescent current is 1.7 mA.

Feature Summary

• Class-D architecture for high efficiency
• Filter-free operation capability
• Integrated pop-and-click suppression
• Thermal shutdown protection

Applications

• Portable media players
• Mobile phones
• Personal digital assistants

Procurement Notes

Verify the specific suffix DRBR against the manufacturer's official datasheet to confirm the tape and reel packaging configuration. Ensure the component meets RoHS compliance requirements for your target market. Confirm that the 8-SON package footprint matches your PCB design constraints before finalizing procurement orders.

Selection Notes

Select this component for applications requiring a compact mono audio solution with low power consumption. The filter-free design reduces external component count compared to other Class-D amplifiers. Consider the thermal performance in enclosed spaces due to the small package size.

Part Context

This part belongs to the TPA2005 series of audio amplifiers designed for portable electronics. It serves as a cost-effective alternative to Class-AB amplifiers while offering higher efficiency. The series is optimized for battery-powered devices where space and power are critical constraints.

Replacement Considerations

Check for direct pin-to-pin replacements within the same family, such as the TPA2005D1DRBT. Verify if upgraded variants with different packaging or enhanced thermal characteristics are available from the manufacturer.
