TPA2100P1YZHR

Overview

The TPA2100P1YZHR is a mono, Class-D audio power amplifier designed for piezo and ceramic speakers. It features an integrated DC-DC converter that generates a boost voltage up to 19 Vpp, enabling high output power from low supply voltages. The device operates on a single supply voltage ranging from 2.5 V to 5.5 V. It includes selectable gain options and analog input functionality. The component is housed in a 16-pin DSBGA package (YZH) and supports operation within a temperature range of -40°C to 85°C.

Feature Summary

• Integrated DC-DC boost converter eliminates external inductors for piezo/ceramic speaker driving
• Mono Class-D architecture optimized for high efficiency with analog input
• Selectable gain configuration allows flexibility in system design
• Compact DSBGA packaging suitable for space-constrained portable applications

Applications

• Piezoelectric speaker drivers in portable devices
• Ceramic resonator or speaker amplification in consumer electronics
• Battery-powered audio systems requiring high efficiency
• Mobile phones and handheld multimedia players

Procurement Notes

Verify the exact suffix YZHR to confirm the 16-pin DSBGA package and specific tape-and-reel quantity. Confirm RoHS compliance status as it may vary by production batch. Ensure the application circuit matches the required boost voltage and gain settings specified in the official datasheet for the TPA2100P1 family.

Selection Notes

Select this part when driving piezo or ceramic loads requiring high peak voltage from a low-voltage battery source. The integrated boost converter simplifies bill of materials compared to discrete solutions. Consider the DSBGA package size constraints and thermal requirements for the target enclosure. Verify that the analog input interface meets the system's signal level requirements.

Part Context

This component belongs to Texas Instruments' NanoFree series of audio amplifiers. It is part of the TPA2100 family, which focuses on simplified designs for small form-factor audio applications. The TPA2100P1 variant specifically targets piezo and ceramic speakers, distinguishing it from standard dynamic speaker amplifiers within the same product line.

Replacement Considerations

Check for TPA2100P1EVM evaluation board availability for prototyping. Verify if other suffixes like TPA2100P1YFFR offer different packaging but identical electrical characteristics. Cross-reference with newer generations of TI nano-free amplifiers if pin compatibility is not required.
