TPA2033D1YZFR

Overview

The TPA2033D1YZFR is a fixed-gain mono Class-D audio power amplifier manufactured by Texas Instruments. It delivers 2.75 W output power into a 4-ohm load at 10% THD+N with a 5 V supply. The device operates on a single supply voltage ranging from 2.5 V to 5.5 V and features a typical quiescent current of 3 mA. It utilizes a fully differential architecture with a gain of 9.5 dB (3 V/V). The component is housed in a lead-free 9-ball Wafer Chip Scale Package (WCSP) measuring approximately 1.5 mm by 1.5 mm.

Feature Summary

• Fully differential design reduces RF rectification and eliminates the need for input coupling capacitors when used with properly biased sources.
• Fixed internal gain configuration removes the requirement for external gain-setting resistors, minimizing the external component count.
• Integrated thermal and short-circuit protection mechanisms safeguard the device during abnormal operating conditions.
• NanoFree lead-free packaging provides a minimal footprint suitable for space-constrained mobile applications.

Applications

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

Procurement Notes

Verify that the ordering suffix YZFR corresponds to the specific tape-and-reel packaging quantity required for production. Confirm the RoHS compliance status matches project specifications. Ensure the supplier documentation references the correct datasheet revision. Validate that the component lot aligns with the expected manufacturing date code for inventory management purposes.

Selection Notes

Select this part when a fixed gain of 3 V/V is required for the audio signal path. The fully differential input topology is advantageous for noisy environments to maximize noise rejection. Consider the 9-DSBGA package dimensions against available PCB real estate. Verify that the target application operates within the specified 2.5 V to 5.5 V supply voltage range.

Part Context

This component belongs to the TPA203xD1 family of filter-free Class-D amplifiers. It shares the same pinout as the TPA2010D1 but integrates internal gain resistors. The family includes variants with different fixed gains: TPA2032D1 (2 V/V), TPA2033D1 (3 V/V), and TPA2034D1 (4 V/V). All variants utilize the same NanoFree package technology.
