TPA2010D1YZFR

Overview

The TPA2010D1 is a 2.5-W mono Class-D audio power amplifier in a 9-pin DSBGA package. It operates on a supply voltage of 2.5 V to 5.5 V with a quiescent current of 2.8 mA and shutdown current of 0.5 µA. The device delivers up to 2.5 W into a 4-Ω load at 5 V, achieving 88% efficiency at 400 mW into an 8-Ω speaker. It features a fully differential design, -75 dB PSRR, and a 250-kHz switching frequency.

Feature Summary

• Fully differential architecture eliminates the need for input coupling capacitors and mid-supply bypass capacitors.
• Optimized PWM output stage removes the requirement for external LC output filters.
• High power supply rejection ratio (-75 dB) and wide operating voltage range eliminate the need for additional voltage regulators.
• Improved common-mode rejection ratio enhances noise immunity in wireless environments.

Applications

• Wireless or cellular handsets
• Personal digital assistants (PDAs)
• Personal navigation devices
• General portable audio devices

Procurement Notes

Verify the specific ordering suffix YZF against the manufacturer's datasheet to confirm lead-free NanoFree™ packaging compliance. Ensure the component matches the exact part number TPA2010D1YZFR to guarantee correct pinout and thermal characteristics. Cross-reference the revision history to confirm the document version aligns with your design requirements.

Selection Notes

Select this component for applications requiring high efficiency and minimal external components. The fully differential inputs are suitable for noisy environments like mobile phones. Verify that the PCB layout accommodates the 1.5 mm x 1.5 mm DSBGA footprint and adheres to the recommended thermal dissipation guidelines for the target ambient temperature.

Part Context

This device belongs to Texas Instruments' filter-free Class-D audio amplifier family. It utilizes a die-size ball grid array (DSBGA) package to minimize board space. The internal oscillator generates a 250-kHz switching frequency, allowing for compact designs without bulky passive components typically required for EMI filtering in traditional Class-D amplifiers.

Replacement Considerations

TPA2005D1: Lower power output (1.4 W). TPA2011D1: Higher power output (3.2 W) and improved PSRR (86 dB).
