TPA2010D1YZFT

Overview

The TPA2010D1YZFT is a 2.5-W mono filter-free Class-D audio power amplifier in a 9-pin DSBGA package. It operates on a 2.5-V to 5.5-V supply with 2.8-mA quiescent current and 0.5-µA shutdown current. The device achieves 88% efficiency at 400 mW into an 8-Ω load and features a -75-dB PSRR. An internal 250-kHz switching frequency eliminates the need for output LC filters, bypass capacitors, or input coupling capacitors.

Feature Summary

• Fully differential architecture reduces RF rectification effects and eliminates the requirement for bypass and input coupling capacitors.
• Optimized PWM modulation scheme removes the necessity for external LC output filters.
• High power supply rejection ratio (-75 dB) combined with wide voltage tolerance allows operation without additional voltage regulators.

Applications

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

Procurement Notes

Verify the specific YZF suffix indicates the NanoFree lead-free variant within the 9-pin DSBGA package. Confirm that the ordering information matches the required thermal and mechanical specifications for the target PCB layout. Ensure compatibility with the intended single-supply voltage range of 2.5 V to 5.5 V.

Selection Notes

Select this component when minimizing external component count and PCB area is critical. The fully differential design is suitable for noisy environments requiring high noise immunity. Verify that the application does not require gain adjustment beyond the fixed internal configuration.

Part Context

This device belongs to Texas Instruments' TPA2010 family of high-efficiency Class-D amplifiers. It utilizes a die-size ball grid array (DSBGA) footprint measuring 1.50 mm by 1.50 mm. The YZF suffix specifically denotes the lead-free NanoFree packaging option compliant with environmental standards.
