TPA2032D1YZFR

Overview

The TPA2032D1YZFR is a 2.75-W fixed-gain mono filter-free Class-D audio power amplifier from Texas Instruments, housed in a 9-ball WCSP (YZF) package. It operates on a single supply voltage ranging from 2.5 V to 5.5 V and features a differential input with a fixed gain of 6 dB (2 V/V). The device delivers high efficiency, reaching 88% at 400 mW into an 8-Ω load, while maintaining low total harmonic distortion plus noise of 0.18%. It includes thermal and short-circuit protection, a 0.5-μA shutdown current, and requires only one external decoupling capacitor.

Feature Summary

• Fully differential architecture eliminates the need for input coupling capacitors and mid-supply bypass capacitors when inputs are biased correctly.
• High electromagnetic interference immunity through optimized PWM output stage and internal matched resistors for superior PSRR and CMRR.
• Integrated thermal and short-circuit protection mechanisms safeguard the device during fault conditions.
• Ultra-low quiescent current and minimal shutdown current maximize battery life in portable wireless applications.

Applications

• Wireless handsets
• Personal Digital Assistants (PDAs)
• Mobile devices

Procurement Notes

Verify that the ordering suffix 'R' corresponds to the tape-and-reel packaging configuration as specified in the manufacturer's documentation. Confirm the YZF package designation matches the required wafer chip scale form factor. Ensure compatibility with the intended PCB layout guidelines for the 9-ball WCSP footprint to maintain electrical performance and reliability standards.

Selection Notes

Select this component for designs requiring a compact, high-efficiency mono audio solution with minimal external components. The fixed 6 dB gain suits applications where signal amplification requirements align with this specific ratio. Consider the differential input topology for improved noise rejection in electrically noisy environments compared to single-ended alternatives.

Part Context

This part belongs to the TPA203xD1 family of NanoFree™ Class-D amplifiers, which shares pinouts and functional similarities with the TPA2010D1 but integrates fixed gain settings. The family includes variants with different gains, such as the TPA2033D1 and TPA2034D1, all utilizing the same small footprint to facilitate space-constrained mobile electronics design.

Replacement Considerations

TPA2032D1YZFT serves as the cut-tape equivalent of the reel-packaged TPA2032D1YZFR. Other family members like TPA2033D1 or TPA2034D1 offer alternative gain levels but require verification of circuit compatibility due to differing voltage gains.
