TPA2015D1YZHR

Overview

The TPA2015D1YZHR is a single-channel Class-D audio power amplifier manufactured by Texas Instruments. It features an integrated adaptive boost converter and SpeakerGuard AGC technology for efficient battery-powered operation. The device delivers up to 2W of output power into an 8-ohm load with 6% THD+N. Key electrical parameters include a supply voltage range of 2.5V to 5.2V, a typical quiescent current of 1.7mA at 3.6V, and a fixed gain of 20dB. It operates within a temperature range of -40°C to +85°C and utilizes a 16-ball DSBGA package measuring 1.954mm x 1.954mm.

Feature Summary

• Integrates an adaptive boost converter to enhance efficiency at low output power levels.
• Includes SpeakerGuard automatic gain control to limit battery current draw and prevent severe clipping.
• Features a built-in low-pass filter to improve RF rejection and reduce out-of-band noise from DACs.

Applications

• Mobile phones
• Personal Digital Assistants (PDAs)
• GPS navigation devices
• Portable electronic equipment

Procurement Notes

Verify the specific suffix YZHR against the official datasheet to confirm the package type and tape-and-reel configuration. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before procurement.

Selection Notes

Select this component when designing battery-operated systems requiring high efficiency and loud audio output from a single cell. The integrated boost converter allows higher voltage swings than direct battery connection. Consider the 1.954mm x 1.954mm footprint for space-constrained layouts. Verify that the 20dB fixed gain aligns with the system's input signal levels.

Part Context

This part belongs to the TPA201xD1 series of mono Class-D amplifiers. It is pin-to-pin compatible with the TPA2013D1. The series is designed specifically for portable applications where power efficiency and audio quality are critical constraints.

Replacement Considerations

The TPA2013D1 is a confirmed pin-to-pin compatible substitute within the same product family. Verify that the replacement part matches the required package marking and electrical characteristics for the specific application design.
