TPA2010D1YEFT

Overview

The TPA2010D1YEFT is a 2.5-W mono Class-D audio power amplifier in a DSBGA-9 package. It operates on a single supply voltage ranging from 2.5 V to 5.5 V. The device delivers high efficiency, reaching 88% at 400 mW into an 8-Ω load and 80% at 100 mW. Key electrical parameters include a quiescent current of 2.8 mA, shutdown current of 0.5 µA, and a switching frequency of 250 kHz. It features a -75 dB PSRR and supports differential inputs with a gain of 2 V/V.

Feature Summary

• Filter-free design utilizing an optimized PWM output stage that eliminates the need for LC output filters.
• Fully differential architecture that reduces RF rectification and removes the requirement for input coupling capacitors.
• High thermal efficiency and low static current consumption to extend battery life in portable devices.

Applications

• Wireless or cellular handsets
• Personal Digital Assistants (PDAs)
• General portable audio devices

Procurement Notes

Verify the specific suffix YZFT against the manufacturer's datasheet to confirm lead-free NanoFree™ packaging compliance. Ensure the ordering part number matches the required pinout configuration for the DSBGA-9 footprint. Cross-reference the revision history to confirm compatibility with existing reference designs.

Selection Notes

Select this component for applications requiring minimal external components and small PCB area. The fully differential input is suitable for noisy environments like wireless handsets. Verify that the system power supply remains within the 2.5 V to 5.5 V range and that the load impedance matches the amplifier's capabilities.

Part Context

This device belongs to Texas Instruments' TPA203x series of filter-free Class-D amplifiers. It shares architectural similarities with the TPA2031D1 but offers distinct performance characteristics tailored for high-efficiency portable audio applications. The DSBGA package allows for compact integration in space-constrained mobile electronics.
